Sinus Bradycardia with Bigeminal PVCs: Understanding Heart Rhythm Abnormalities

A sinus bradycardia with Bigeminal PVCs is a unique heart rhythm abnormality that can be seen on an electrocardiogram (ECG). This condition involves two distinct components: sinus bradycardia and Bigeminal PVCs.

Sinus bradycardia is a condition where the heart beats at a slower rate than the normal range, typically defined as less than 60 beats per minute. On the other hand, Bigeminal PVCs (premature ventricular contractions) are extra heartbeats that occur in a specific repeating pattern, with every other beat being a premature contraction originating from the ventricles of the heart.

When these two components are present together in a heart rhythm, it indicates that the heart is not only beating slower than usual but also experiencing additional premature contractions that disrupt the normal cardiac cycle. This abnormality can have different causes and implications depending on the individual patient's overall health and cardiac function.
