Insights
Pacemakers can interfere with electrocardiogram (ECG) accuracy for diagnosing myocardial ischemia. This case highlights challenges in identifying myocardial infarction during biventricular pacing due to a lack of established ECG criteria.
Area of Science:
- Cardiology
- Medical Diagnostics
- Electrophysiology
Background:
- Pacemakers are crucial for managing heart rhythm disorders.
- Electrocardiograms (ECGs) are vital for diagnosing myocardial ischemia.
- Pacemaker activity can alter ECG interpretation, potentially affecting diagnostic accuracy.
Abstract:
Pacemakers devaluate the accuracy of the electrocardiogram (ECG) for the diagnosis of myocardial ischaemia. We present the case of a 53-year-old man with ischaemic cardiomyopathy and acute chest pain. Besides biventricular pacing, new ST-segment elevations were present leading to the diagnosis of myocardial infarction. However, no ECG criteria for the diagnosis of myocardial ischaemia in biventricular-paced rhythm are available.

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...

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.
