Abstract

Heart rate variability (HRV) is sensitive to the changes of the autonomic activity and decreases in looming morbidity of cardiovascular system due to autonomic dysfunction. In heart block or atrial flutter or atrial tachycardia, HRV with high power reported with cluster pattern on Poincaré plot which could be due to low voltage QRS complex beats which were not picked by software for HRV analysis. Picking those beats using custom settings included the beats and reported true HRV of the patient reflecting autonomic activity.

Beats not picked at around 20, 24, 28 sec
