Ventricular Bigeminy: Understanding the Rhythm of Your Heart

What is ventricular bigeminy and how does it manifest on an ECG?

Ventricular Bigeminy Explained:

Ventricular bigeminy occurs when every second complex on an ECG is a premature ventricular contraction (PVC). This pattern of one normal beat followed by a PVC repeats consistently and is a specific type of cardiac arrhythmia.

Understanding ventricular bigeminy involves recognizing the patterns on an electrocardiogram (ECG), where a PVC appears as an aberrant QRS complex. This arrhythmia lies within the broader category of ventricular arrhythmias, which are due to issues with the heart's electrical conduction system.

In the context of an ECG reading, a normal heartbeat is seen as a standard P wave followed by a QRS complex and then a T wave. In bigeminy, after every regular beat, there's an early beat (the PVC), typically resulting in a rhythm where every alternate beat is abnormal.

Management of this condition may require medical attention as it can be associated with underlying heart disease. Thus, routine evaluation and monitoring through ECG, and possibly a Holter monitor, are pertinent for individuals exhibiting such arrhythmic patterns.

Delving into the Details of Ventricular Bigeminy:

Ventricular bigeminy is a type of cardiac arrhythmia characterized by the occurrence of a normal heartbeat followed by a premature ventricular contraction (PVC), and this pattern repeats consistently. Thus, the correct answer to the question 'Ventricular bigeminy occurs when' is D. Every second complex is a PVC.
