Paroxysmal supraventricular tachycardia (PSVT) can cause a person’s heart rate to spike suddenly, then return abruptly to the usual rate. What causes a sudden spike in heart rate when resting? Here are some questions people often ask about changes in heart rate. If these methods do not provide relief and the symptoms become severe, a hospital can provide intravenous fluids. Sachets of oral rehydrate are available at most chemists. If symptoms of dehydration occur, oral rehydration solutions can provide electrolytes quickly, enabling fast absorption.

The word supraventricular means that the arrhythmia originates from the top chamber of the heart. Instead, it causes it to originate in another part of the top chamber of the heart. This prevents the heartbeat from originating in the sinoatrial node, which creates sinus rhythm. Supraventricular tachycardia can happen when there is a problem with the heart’s electrical circuit or a heartbeat originates in the atrium outside of the sinus node. Learn more about the types of sinus tachycardia here. It could be the result of a nerve-signaling problem in the heart. Inappropriate sinus tachycardia, which is rare, occurs when the heart rate increases for no apparent reason. Sinus tachycardia occurs when the heart rate increases due to expected reasons, such as during exercise, if a person is feeling anxious, or during periods of dehydration.
