The SA node (called the pacemaker of the heart) sends out an electrical impulse. The upper heart chambers (atria) contract. The AV node sends an impulse into the ventricles.
What causes electrical impulses in the heart?
An electrical stimulus is generated by the sinus node (also called the sinoatrial node, or SA node). This is a small mass of specialized tissue located in the right upper chamber (atria) of the heart. The sinus node generates an electrical stimulus regularly, 60 to 100 times per minute under normal conditions.
What causes damage to heart’s electrical system?
It can also be caused by problems with your heart function such as heart failure or leaky heart valves. Sometimes surgical intervention can also bring on this kind of problem. If these rhythm disturbances come from the upper chambers of the heart, they are called atrial arrhythmias (abnormal rhythms of the heartbeat).
What controls the electrical system of the heart?
The electrical impulse starts on the right side of the upper chamber in an area called the sinus node. The sinus node is the normal pacemaker of the heart and controls the heart rate.
How do you fix electrical problems with your heart?
Typically, surgeons defibrillate the heart—send it a controlled electrical shock—to reset the electrical system, and then implant a pacemaker or defibrillator to maintain it.
What is the heart’s electrical system called?
The SA node (called the pacemaker of the heart) sends out an electrical impulse. The upper heart chambers (atria) contract. The AV node sends an impulse into the ventricles. The lower heart chambers (ventricles) contract or pump.
What are electrical impulses in the brain?
Neurons in the brain communicate via rapid electrical impulses that allow the brain to coordinate behavior, sensation, thoughts, and emotion.
How do you check an electrical heart?
An electrophysiology (EP) study is a test performed to assess your heart’s electrical system or activity and is used to diagnose abnormal heartbeats or arrhythmia. The test is performed by inserting catheters and then wire electrodes, which measure electrical activity, through blood vessels that enter the heart.
How can I fix my irregular heartbeat naturally?

Can most heart problems be fixed?
A: Although we can’t cure heart disease, we can make it better. Most forms of heart disease are very treatable today. There is some evidence that normalizing high blood pressure and lowering cholesterol to very low levels will partially reverse plaques in the coronary arteries.
How can I strengthen my heart naturally?

What is the pathway of the heart?
Right side of the heart
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
Does the heart produce electricity?
The heart generates its own electrical signal (also called an electrical impulse), which can be recorded by placing electrodes on the chest. This is called an electrocardiogram (ECG, or EKG). The cardiac electrical signal controls the heartbeat in two ways.
