Palpitations are perceived abnormalities of the heartbeat characterized by awareness of cardiac muscle contractions in the chest, which is further characterized by the hard, fast and/or irregular beatings of the heart. [1] Symptoms include a rapid pulsation, an abnormally rapid or irregular beating of the heart. [1]
Otherwise symptoms may include palpitations, feeling lightheaded, sweating, shortness of breath, and chest pain. [2] The cause is not known. [3] Risk factors include alcohol, psychostimulants such as caffeine, nicotine, and amphetamines, psychological stress, and Wolff-Parkinson-White syndrome, which often is inherited. [3]
Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
Dr. Patwa says that heart palpitations are tied to the heart's electrical conduction system, a network of muscle cells in the heart’s wall that control heartbeats’ rate and rhythm. “The ...
The most common symptom of arrhythmia is an awareness of an abnormal heartbeat, called palpitations. These may be infrequent, frequent, or continuous. Some of these arrhythmias are harmless (though distracting for patients) but some of them predispose to adverse outcomes. Arrhythmias also cause chest pain and shortness of breath. [citation needed]
A premature ventricular contraction (PVC) is a common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node.PVCs may cause no symptoms or may be perceived as a "skipped beat" or felt as palpitations in the chest.
Mobile device management (MDM) is the administration of mobile devices, such as smartphones, tablet computers, and laptops.MDM is usually implemented with the use of a third-party product that has management features for particular vendors of mobile devices.
[1] [5] People with TIC may have symptoms associated with heart failure (e.g. shortness of breath or ankle swelling) and/or symptoms related to the tachycardia or arrhythmia (e.g. palpitations). [1] [2] Though atrial fibrillation is the most common cause of TIC, several tachycardias and arrhythmias have been associated with the disease. [5] [1]
