Your heart is beating normally albeit very strongly.聽 I can clearly hear the blood flow and opening/closing of your tricuspid valve. It beating at 56bpm minute and I could listen to it all day.
Dad checking his boy's heart beat before their breeding session. Heart rate is 57, BP 115/75. The mitral valve is snappy and clear as his warm blood is pumped through the strongly beating muscle.
I want you to take the stethoscope and start just to my left and just under the pec. Listen to the mitral and begin moving around to my tricuspid, erbs point and pulmonary valves. Listen for the blood flow and valve snap while I'm at my resting heart rate. I'll lay down if you like. Afterwards, hook me up to the EKG and see how well its pumping.
