Lying on your left side can stimulate the vagus nerve, sending abnormal electrical signals to the heart causing palpitations. It is responsible for controlling the heart rate. This is an important nerve that reaches from the brain to the abdomen. The easiest fix for this is to simply change position.Įxperiencing heart palpitations when lying down on the left side may be from activating the vagus nerve. When you lay down you compress the stomach and chest cavity together, putting pressure on the heart and blood flow and increasing circulation. Patients may ask, "Why does my heart beat fast when I lay down?" Most often palpitations are caused by the change in position of the body. Some people experience their heart beating fast at night and can't sleep. They can occur at different times for different reasons, according to the National Institutes of Health's National Heart, Lung, and Blood Institute. It can also be the feeling of having a fast heartbeat or the feeling that the heart is pounding strongly. Heart palpitations is the feeling of having heart flutters when lying down. This is a common occurrence for many people and often does not indicate a serious problem. The scar tissue does not conduct electricity as it interferes with stray electrical impulses that lead to increased heart rate.The feeling that your heart is racing when lying down is commonly known as heart palpitations. In another type of surgery called the maze procedure, small incisions are made in heart tissue to create a maze (a pattern) of scar tissue. Surgery: In some cases, open-heart surgery may be necessary to destroy an extra electrical pathway. It is recommended in life-threatening conditions of rapid heartbeat. The ICD continuously monitors heartbeat and detects an increase in heart rate, and delivers precisely calibrated electrical shocks, thereby restoring a normal heart rhythm. Implantable Cardioverter-Defibrillator (ICD): It is surgically implanted into the chest. When the pacemaker detects an abnormal heartbeat, it emits an electrical pulse to resume a normal heartbeat. Implantable Pacemaker: It is surgically implanted under the skin. It can also be used to treat atrial fibrillation and atrial flutter. This procedure is highly effective for supraventricular tachycardia. Electrodes at the catheter tips use heat, extreme cold or radiofrequency energy to ablate the extra electrical pathway, preventing it from sending electrical signals. It is preferred when maneuvers and medications are ineffective.Ĭatheter Ablation: In this procedure, the doctor inserts the catheter into the groin, arm or neck and guides them through the blood vessels to the heart. The current affects the electrical impulses in the heart and restores a normal rhythm. Some other medications that may be prescribed in combination with anti-arrhythmic medications are calcium channel blockers or beta-blockers.Ĭardioversion: In this procedure, a shock is delivered to the heart through paddles or patches on the chest. Oral anti-arrhythmic drugs are also prescribed by doctors. If vagal maneuvers do not stop the fast heartbeat, an anti-arrhythmic medication (intravenous) is required to restore a normal heart rate. The maneuvers include coughing, bearing down, and putting an ice pack on the face. It affects the vagus nerve that helps regulate the heartbeat. The heart rate can be decreased by Vagal manoeuvers. The treatment for tachycardia aims to slow down the heart rate, prevent future episodes and minimize complications. The doctor observes how the heart and the nervous system responds to the changes in position. The patient will be asked to lie flat on a special table, and then the table is tilted as if the patient is standing up. Tilt Table Test: This test helps to understand how tachycardia contributes to fainting spells. The electrodes can precisely map the spread of electrical impulses during each beat and identify the abnormalities in the circuitry. Different patterns among the signals are determined to identify abnormalities in the heart rate.Įlectrophysiological Test: It is used to confirm the diagnosis or to pinpoint the location of problems in the heart's circuitry.ĭuring this test, a thin, flexible catheter tipped with electrodes is placed on the groin, arm or neck and guided through the blood vessels to various spots in the heart. For performing ECG, small sensors are attached to the chest and arms of the patient to record the electrical signals that travel through the heart. The diagnosis of tachycardia includes a physical examination with several other tests such as:Įlectrocardiogram (ECG): It is a primary tool for diagnosing rapid heart rate.
