This term is connected with the thumping of the throat, neck or chest and the departures of the heart’s normal rhythm are the cause of this problem. This problem may be experienced frequently but it can also be very rare. Also, some other condition can cause it or it can come very suddenly and unexpectedly. If the problem is happening occasionally, the cause must be found. But, sometimes the problem may occur in a healthy individual. If the serious palpitations are experienced, problems like heart disease can be the cause. The normal heart rhythm is in the region of 50 to 100 beats per minute. These beats are caused by the electrical impulses sent by the sinus node, which is a region of the heart. The four chambers of the heart are stimulated in this process and in this way, the blood moves to every part of the body from the chambers. Sometimes the heartbeat can be increased, which usually happens because of the chemicals and nervous reactions. One of them is adrenaline.
Tachycardia is the increased heartbeat, which goes over the 100 beats per minute. The problem with slow heartbeat is called bradycardia and it is associated with heartbeat lower than 50 beats per minute. A person can feel a thump, which is a one extra beat of the heart. This is called ectopic beat and it is experienced once in every 34 hours. Supraventricular and ventricular are two types of tachycardia. Supraventricular tachycardia is caused by the rapid electrical activity in the upper chambers of the heart. This problem is associated with heart rate in the region of 140 to 240 beats and dizziness and it can last for several minutes or it can be very brief. When the abnormal electrical pathway receives the impulses sent from the sinus node, the problem called pre-existing syndrome is present. Ventricular tachycardia is not common as other type. This problem is associated with the heartbeat from 120 to 200 in the larger chambers and it causes no change in the heartbeat change in the small chambers. If this problem is present, visit to the hospital is needed. Atrial fibrillation is associated with 400 beats per minute of the atria, while the heart rate of the ventricles is 280 beats. It affects the pumping of the heart and leads to loss of breath. The treatment is needed for this irregular heartbeat.
Symptoms and Treatment
The most common symptoms are disorientation, perspiration, chest pain, fainting, loss of breath, dizziness and others. The symptoms are sometimes hard to notice. Cardioversion is method used for treatment and it involves electrical shocks. Another treatment is pacemaker implant, along with the catheter ablation therapy. The surgical defibrillator implantation is also a possibility.
