Many people may have heart rhythm disturbances and never be aware of them. Premature atrial contractions (PACs) andpremature ventricular contractions(PVCs) are variations of normal and most often, people are unaware that an extra beat has occurred. However, some patients are keenly aware of any e...
Tracking of congestion with cardiac filling pressures or lung water content has shown most impact to decrease hospitalizations, while multiparameter scores from implanted rhythm devices have identified patients at increased risk. Algorithms require better personalization of signal thresholds and interventions....
But various forms of arrhythmia (abnormal heart rhythms) are trickier. This is where the electronics come in. They may have a genetic component, but they can also be influenced by stress and intense training. Arrhythmia is a generic label for a condition in which the heart rhythm is altered ...
They happen when your heart's ventricles squeeze too soon. The extra beat throws off your heart's normal rhythm and makes it flutter, pound, or jump in your chest. If your heart is healthy, occasional PVCs are nothing to worry about. But you might need treatment if you have heart ...
During normal sinus rhythm, the heart rate (HR) varies from beat to beat. Heart rate variability (HRV) results from the dynamic interplay between the multiple physiologic mechanisms that regulate the instantaneous HR. Since short-t...

The appearance of this arrhythmia during anaesthesia on any other occasion is cause for concern as this rhythm may progress within a few minutes to advanced heart block (P waves only, no ventricular complexes) and cardiac arrest. Atrial fibrillation and PVCs occur rarely in horses but may ...
Arrhythmias, or irregular heartbeats, occur when the electrical signals that control the heart's rhythm are disrupted. While some arrhythmias are harmless, others can indicate underlying health conditions. Fortunately, natural remedies, including dietary changes, herbal supplements, and lifestyle ...
Atrioventricular (AV) Node:A group of special cells located near the center of the heart that helps to regulate the heart rhythm. Here, the electrical current slows for a moment before going on to the ventricles. Atrium:The top chamber of the heart. There are two atria -- the left and ...
Before you see a doctor, try some simple things first. Skips of the heart rhythm, low power, fatigue, and irritability often improve with rest and nutrition. Although many athletes find any period without exercise challenging, either a short period of rest or an even longer period of prolonged...
