Patients in the rhythm control arm had fewer HF symptoms than those in the rate control arm. Stable sinus rhythm was associated with the best functional status. Patients who are the most symptomatic in AF but are unable to maintain normal sinus rhythm if treated by the means used in the ...
Artefact-free 60-second strips of normal sinus-rhythm ECGs were converted to binary strings using threshold crossing, beat detection and a novel feature detection parsing algorithm. Complexity of the resulting binary strings was calculated using Lempel-Ziv ('76 & '78) and Titchener complexity ...
Heart rate variability does not mean you have an arrhythmia or abnormal heartbeat. Measured in milliseconds, this is the time shown from ‘R peaks” in the heart’s electrical pattern. In normal sinus rhythm, or the normal heartbeat, the variability between heartbeats is less than 0.12 seconds...

A“normal” pulse rate depends on various factors. For example, in addition to the weather, time of day, medication or illnesses, the resting pulse rate is mainly dependent on physical condition and age. Gender also plays a role: women often have a slightly higher heart rate than men.8 ...

A prolonged P-wave duration (PWD) in sinus rhythm pre-ablation has been hypothesized to be a non-invasive ECG marker associated with increased atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI). This systematic review and meta-analysis will assess the latest evidence on the...
