In a bigeminy pattern, how often does a PVC occur?

In a bigeminy pattern, a PVC (premature ventricular contraction) occurs every second beat. This means that after a normal heart beat, a PVC follows, creating a rhythm that alternates between normal and premature beats. This alternating rhythm can lead to a characteristic regularity in the pulse, where the regular beats are interspersed with the premature contractions.

Understanding the frequency of these PVCs in relation to normal heartbeats is essential for recognizing this pattern on an ECG. This knowledge allows healthcare providers to monitor potential disturbances in heart rhythm and assess the underlying causes or implications for patient health. A bigeminy pattern can often be mistaken for other arrhythmias, so recognizing that these irregularities occur every second beat is crucial in clinical practice to make appropriate treatment decisions.
