Insights

Pacing-induced cardiomyopathy (PICM) can affect patients with coronary artery disease (CAD) even with preserved ejection fraction. This report discusses three cases, highlighting the need for further research on managing PICM in this population.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Cardiomyopathy Research

Background:

  • Pacing-induced cardiomyopathy (PICM) is characterized by reduced left ventricular ejection fraction (LVEF) due to chronic, high-burden right ventricular pacing.
  • Cardiac resynchronization therapy (CRT) and conduction system pacing (CSP) are potential management strategies for PICM.
  • Acute myocardial infarction is a known predictor of PICM, but guidelines for CRT/CSP in patients with coronary artery disease (CAD) and preserved LVEF are lacking.

Mechanism of Cardiac Arrhythmias01:28

Mechanism of Cardiac Arrhythmias

Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
