Abstract:
We describe a case of primary lung cancer with myocardial metastasis, documented with electrocardiogram (ECG) mimicking myocardial ischemia and manifesting VT. Metastatic tumor to the myocardium proper is uncommon and difficult to diagnose because of nonspecific signs and symptoms. We observed such ECG changes in this case were initially misinterpreted as acute coronary syndrome. The diagnosis of cardiac metastasis was confirmed by contrast-enhanced magnetic resonance imaging and computed tomography.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

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.
