what happens if only half your heart is working?

So when you have right-side heart failure, the right chamber has lost its ability to pump. That means your heart can't fill with enough blood, and the blood backs up into the veins. If this happens, your legs, ankles, and belly often swell.

PVCs become more of a concern if they happen frequently. “If more than 10% to 15% of a person's heartbeats in 24 hours are PVCs, that's excessive,” Bentz said. The more PVCs occur, the more they can potentially cause a condition called cardiomyopathy (a weakened heart muscle).

A heart rate slower than 60 is called bradycardia. An occasional extra heartbeat is known as extrasystole. Palpitations are not serious most of the time. Sensations representing an abnormal heart rhythm (arrhythmia) may be more serious.

The Heart Responds Broken heart symptoms, such as chest tightness and shortness of breath, can seem like a heart attack. The problem happens when psychological distress triggers sudden weakness of the heart muscle. It can be caused by sudden shock or acute anxiety.

Unless a heart condition is causing your heart palpitations, there's little risk of complications. For palpitations caused by a heart condition, possible complications include: Fainting. If your heart beats rapidly, your blood pressure can drop, causing you to faint.

Bigeminy can raise your risk of developing an arrhythmia such as atrial fibrillation, in which the upper chambers of your heart don't beat in a coordinated pattern with the lower chambers. When this happens, blood can pool in your atria and a clot can form.

Overworking your heart causes the heart muscle to thicken, like any muscle being worked strenuously. Over time, this can lead to atrial fibrillation, and to heart failure.

But if you have AFib and your heart is beating too slowly, your doctor may recommend a pacemaker along with other treatment. It sends out electrical pulses that take the place of the mixed-up ones, so your heart beats at the right pace. You also might need a pacemaker if you have AFib and congestive heart failure.

A heart attack happens when the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked and the heart can't get oxygen. If blood flow isn't restored quickly, the section of heart muscle begins to die. Heart attack treatment works best when it's given right after symptoms occur.

When you have SVT, the electrical system in your heart isn't working right. You might experience a sudden rapid heartbeat, which can lead to shortness of breath, chest pain and, in rare cases, loss of consciousness. SVT often ends suddenly. It stops either on its own or when you take an action to slow your heart rate.

But if you have AFib, your heart's upper chambers -- the atria -- are out of sync. They don't have that nice steady rhythm. Instead, they might be quivering like Jell-O. With heart failure, the muscles of your heart are too weak to pump enough blood, so you don't get the oxygen you need.

Some people who have atrial fibrillation have significant problems with their heart and with exercise, the heart rate can race tremendously during atrial fibrillation, thereby exacerbating the underlying heart condition and may lead to problems such as very low blood pressure, heart failure or a loss of consciousness.

40 to 55% – Below normal heart function. Can indicate previous heart damage from heart attack or cardiomyopathy. Higher than 75% – Can indicate a heart condition like hypertrophic cardiomyopathy, a common cause of sudden cardiac arrest. Less than 40% – May confirm the diagnosis of heart failure.

How does AFib lead to heart failure? Heart failure means the heart isn't pumping enough blood to meet the body's needs. AFib can lead to heart failure because the heart is beating so fast that it never properly fills up with blood to pump out to the body.

In a heart attack, blood flow to the heart is blocked and heart muscle dies. This leads to ventricular fibrillation, which means the main ventricles of your heart are not pumping. In atrial fibrillation the upper chambers of the heart are pumping chaotically, but the ventricles are still doing their job," says A.

Full code. This means that in the event that your heart stops working or you are found to have no pulse, the health care professionals will start chest compressions and/or administer an electrical shock in attempt to resuscitate your heart.
