Random post but when i had cardiac surgery i had this little heart monitor with me at all times, even during surgery itself and the nurses said i should name it as it would always be with me.

Slight tw for picture!!

Last week I found this card my sister made me while cleaning out my closet

Which is relevant because today's the 11th? 12th? (I don't remember which year it happened actually) anniversary of me undergoing a small heart procedure. Doing so has allowed me to stay up late, drink caffeine, stress out, and generally exert myself without fainting. Although I am grateful that this condition gave me the chance to compare and contrast different ERs (best was University College Hospital in London, worst was George Washington University Hospital in DC), life's been a million times better since then. I think if I hadn't gotten a second opinion and kept living with my funky node problem, I would have spent most of 2020 unconscious.

Shout out to the nurse who assured me beforehand: Don't worry, we're going to numb you. In your groin. It's going to feel like a lot of bee stings.

Me: Huh. That's exactly where I've never wanted to feel a lot of bee stings.

Cardiac ablation is the most effective treatment for arrhythmias.

Cardiac arrhythmias, also called arrhythmias, are problems for patients and can be life-threatening in some cases. Arrhythmias cause problems for several hundred thousand people in Poland. Arrhythmias can be treated in a number of ways, but ablation is the most effective. What is ablation, who can get it, and what are the reasons it shouldn’t be done? What is ablation, and what is the…

I had SVT, ended up having an ablation. Things that triggered it included but we’re not limited to:

Standing up too fast

Bending down too fast

The pressure of pool water around my chest

Playing the viola (deep notes that vibrates in my chest were the worst)

Coughing

Opening a door

Beta blocker didn’t help me, so ablation was the next step.

I ATE TOO MANY POTATO AGAIN

Pulsed Field Ablation: The Next Big Thing In Medical Device Technology

Advancements in medical device technology are helping doctors treat conditions in less invasive ways. One such innovation is pulsed field ablation (PFA), a new method for treating cardiac arrhythmias without the need for open-heart surgery. This cutting-edge technique uses pulsed electric fields to safely create precise non-thermal lesions in the heart muscle.

How Does PFA Work?

Pulsed Field Ablation works by delivering high-intensity electric pulses to targeted cardiac tissue through electrodes. These nanosecond pulses are able to penetrate cell membranes without causing irreversible electroporation, thereby ablating the tissue in a non-thermal manner. The electric fields disrupt cell membranes only in the immediate vicinity of the electrodes, allowing for creation of very precise and controlled lesions without affecting surrounding healthy tissues.

  This is a major advantage over older ablation techniques that rely on temperatures to ablate. With PFA, there is no thermal energy transfer so the risk of collateral damage is minimized. Researchers have demonstrated in animal studies that PFA can accurately target and treat arrhythmias with precise ablation lesions and no perforation of cardiac chambers.

Potential For Treating Complex Arrhythmias

Pulsed field ablation shows great potential for treating complex arrhythmias that have been difficult to manage using existing techniques. Its ability to create tailored, millimeter-sized lesions could help treat conditions like atrial fibrillation originating from multiple focal points in the heart muscle. Precisely targeting these areas is challenging with temperature-based radiofrequency ablation. 

PFA may also help defeat arrhythmias located near arteries, veins or conducting tissues where thermal energy risks unintended coagulation or vessel damage. The elimination of thermal effects makes it safer for treating arrhythmias very close to the esophagus as well. Its non-thermal mechanism could expand treatment eligibility for elderly patients or those with comorbidities precluding the heat effects of older ablation technologies.

Clinical Trial Results Are Promising 

Several medical technology companies are developing PFA systems and have initiated early human trials. Results so far have been very encouraging. In a 30-patient study of PFA for atrial fibrillation, symptoms were successfully eliminated in over 90% of participants with no serious adverse events. Follow-up showed the majority remained arrhythmia-free over a year later.

Another trial on 25 patients with recurrent ventricular tachycardia or ventricular fibrillation after heart attack also demonstrated strong efficacy and safety. Over 80% of participants saw complete resolution of their arrhythmia episodes post-ablation. Key investigators noted the consistent, homogenous lesions achieved with PFA were larger than anticipated and resulted in fewer treatment touches compared to standard radiofrequency ablation.

Regulatory Approval And Commercialization Plans

Given these positive results, manufacturers are working to seek regulatory clearances from the FDA and CE Mark approval in Europe over the next 1-2 years to commercially launch PFA systems. With approval, PFA could start replacing radiofrequency as the primary approach for most catheter ablations by 2025 according to analysts. Billing codes are also being established to ensure insurance coverage.

This innovation could be highly transformative for the multi-billion dollar cardiac ablation device  if large clinical trials confirm its advantages over legacy technologies. Hospitals stand to benefit from shorter procedure times, reduced complication risks and ability to treat more complex cases. For patients, PFA promises less invasive and more effective treatment of cardiac arrhythmias without the side effects of temperature-based ablation. Its arrival could help address the growing epidemic of atrial fibrillation worldwide.

Pulsed field ablation is an exciting new method for cardiac ablation that overcomes many limitations of existing temperature-based techniques. Early human data validates its superior safety profile and ability to precisely target arrhythmias. Regulatory clearances in the next two years should enable the commercial launch of PFA systems. This technology could revolutionize the field of electrophysiology and meet a major unmet need in arrhythmia care. Pending larger clinical outcomes, PFA appears well poised to become the new gold standard for catheter ablation procedures.

Today marks my 7 month anniversary for my cardiac surgery. So id like to share my experience with SVT in honour of the doctors who have saved my life.

Also just in case people are interested!! Because honestly, its a very interesting condition.

As i said, its been 7 months since my surgery. Im forever greatful for my surgeons. Since its 7 months, i now experience no palpitations, which is awesome. Before it happened maybe daily? I feel non now. Its the best thing ive ever done.

Right, let me explain SVT first.

SVT stands for supraventricular tachycardia. Its when theres an additional pathway in the hearts electrical circuit, leading to the heart beating abnormally fast for an hour up to a day at a time.

Anyway.

I was diagnosed at the age of 4, in the US. I was visiting my grandparents and i was sent ro multiple hospitals to get diagnosed. A specialist took me in and finally got me sorted. Ever since then, it has been a struggle.

Ive been on adenosise a a lot, sometimes a few doses at once as i was almost immune to it. Ive been in perri arrest (stage before cardiac arrest) around 3 times. I have been sedated once. I have a massive fear of neddles because of my experiences with them in hospital. I have been pinned down tons of times.

My the age of 8, i was on the strongest medication with the highest dose with two medications. Its very dangerous to take them both together, that now severe my condition was. A year ago, i was taken in by the famous hospital in london under their cardiac unit. My cardiologists finally decided to give me the cardiac ablation.

The cardiac ablation works like this:

9 slits are made near the groin, 5 on one side, 4 on another. Catheters are inserted into the veins and arteries up to the heart. They put you into an episode of SVT to find the extra parhway. Once found, they either burn it or freeze it off, scarring the heart safely. Everything is removed with no stitches at all.

My surgery went fine, textbook easy. I have 4 tiny scars near my groin/on my thigh. I experiences daily heart palpitations at resting for about 6 months, which is normal.

Recovery was easy. It was extremely hard to walk, thats all. Legs were extremely weak and your heart just feels a bit funny, with the beating i mean. I could definitely feel a difference. I just couldn't be on my side for the first few days, making sleeping uncomfortable.

Theres my experience!! It was a journey definitely, but im so glad i overcame it <3.

It's been a tough day at the clinic for this young doctor. She spent hours running here and there to visit a flood of patients that during those torrid days are more numerous than ever (and more impatient than even). The overload of stress made itfself felt and her heart condition became pretty intrusive. Her heart has thrown brief episode of tachycardia for the last few hours, nothing to worry about, she's completely aware of it, but sometimes it makes her quite breathless. Fortunately her shift is ending and now the clinic is almost empty. Alone in her study, she decides to take a rest and auscultate herself a little bit to calm down, a practice that helped her before. She's standing in the middle of the room with the roller shutters slightely lowered to reduce the brightness. She unbuttons her medical coat and does the same with her sky-blue shirt exposing her chest. She takes her stethoscope and, eyes closed, she places the bell over her most favourite spot: her apex. Even if it's quite hard to find given her breast size, the sound is perfectly clear there. She starts listening.

"Lub dub, Lub dub, lub dub" her quite elevated heart rate calms down almost immediately. The quietude is sometimes still interrupted by those tachyarrhythmias. She knows it's nothing to worry about given the situation so she actually ejoys them too.

She has been diagnosed with a condition called Wolff-Parkinson-White syndrome. In her heart the electrical conduction system is a little more complicated and some accessory pathways can make some mess in her heart rhythm. The atrial conduction system can communicate with the ventricle one with a shortcut and the electrical impulse can completely bypass the atrioventricular node that in a normal heart works as a gatekeeper between the two anatomical parts. To make a very complicated thing easyer, this condition can realize two main possibilities: - pre-excitation state that has no symptoms but can be clearly seen during ECG. - electrical loops that keep moving through the heart creating tachyahrrythmias that can span between 150 bpm to more than 200 bpm and can last for few seconds to hours. In this case symptoms are palpitations, dizziness, shortness of breath, sometimes syncope (fainting). There's also a small probability of sudden cardiac death even if it's rare. Things can be dangerous in older people or when atrial flutter/fibrillation is present, in this case the fibrillation can easily spread to the ventricles.

In the case tachyarrhythmias last too long cardioversion is possible, otherwise the most common treatment is through medications. Catheter ablation is also possible with the physical destruction of the electrical shortcuts.
