Extra Electrical Pulse In Heart

This rate is controlled by electrical signals within the heart.

Extra electrical pulse in heart. Tachycardia or rapid heart rate may produce either a regular. Wolff parkinson white wpw syndrome is a relatively common heart condition that causes the heart to beat abnormally fast for periods of time. The syndrome also is associated with some forms of congenital heart disease such as ebstein anomaly. In fact damage to the electrical system of the heart is often the cause of sudden death with a heart attack even if the damage to the heart caused by the heart attack is only mild or moderate.

Another type of svt is called wolff parkinson white syndrome where an abnormal electrical connection occurs between the atria upper heart chambers and ventricles lower heart chambers. The extra electrical pathway that causes a rapid heartbeat is present at birth. Wolff parkinson white syndrome wpw occurs when the heart has an extra electrical pathway. Heart arrhythmia treatment can often control or eliminate fast slow or irregular heartbeats.

The sinus node is the normal pacemaker of the heart and controls the heart rate. Normal heart electrical system. The electrical impulse starts on the right side of the upper chamber in an area called the sinus node. People with wolff parkinson white syndrome are born with a strand of extra muscle tissue between these chambers.

Otherwise little is known about why the extra pathway develops. An abnormal gene is the cause in a small percentage of people with wpw. It results in tachycardia or a rapid heartbeat. A normal resting heart rate for an adult is between 60 and 100 beats per minute.

The cause is an extra electrical connection in the heart. The heart normally beats faster when you are exercising or excited and it beats more slowly when you are at rest or sleeping. Heart disease can lead to abnormalities in your heart s electrical system much as a house damaged in a tornado or flood might have problems with the electrical system. Symptoms include dizziness and fainting tightness in.

This can trigger the rapid heartbeat. If you have it there s an extra pathway in your heart that causes an electrical signal to circle around and around instead of moving down to the ventricles. In addition because troublesome heart arrhythmias are often made worse or are even caused by a weak or damaged heart you may be able to reduce your arrhythmia risk by adopting a heart healthy lifestyle.
