Abstract:
A 73-year-old man with atrial fibrillation and coronary disease requiring stenting to the right coronary artery 7 months prior was admitted for observation after taking an extra dofetilide dose. Troponins trended upward, and electrocardiogram demonstrated QT prolongation to 502 ms as well as T-wave inversions. The patient underwent cardiac catheterization, which revealed severe distal left main disease.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
