During initiation of the cardiac action potential, however, when the negative internal charge of the cell becomes positive so that the cell becomes "depolarized," the researchers found that both ...

When these channels are blocked, the action potential of cardiac cells becomes shorter. The phrase “action potential” describes a change in the charge of a membrane associated with the ...

New imaging algorithm developed recently can diagnose and localize source of atrial fibrillation (a type of rhythm disturbance in the heart) without the need for doing any invasive heart procedures.

A shorter action potential can facilitate the occurrence of the fatal arrhythmias that cause sudden cardiac arrest. High-dose nifedipine (60 mg) caused more shortening of the action potential than ...
