What is sinus bradycardia with right ventricular hypertrophy?
You will find the article below interesting, and informative and I have tried to summarize the answer: Sinus bradycardia: A regular but unusually slow heart beat (60 beats/minute or less at rest). Sinus bradycardia can be the result of many things including good physical fitness, medications, and some forms of heart block. “Sinus” refers to the sinus node, the heart’s natural pacemaker which creates the normal regular heartbeat. “Bradycardia” means that the heart rate is slower than normal. Fainting can occur with sinus bradycardia if the heart slows down even more. This can occur, for example, when the vagus nerve sends a signal to the heart that suddenly drops the heart rate.

Bush has sinus bradycardia and had an episode of fainting due to a vasovagal response after choking on a pretzel. Your heart muscle responds to an increased workload much like your arm muscles respond to wei
