what does it mean if your heart is only working at 35 percent?

If you have an EF of less than 35%, you have a greater risk of life-threatening irregular heartbeats that can cause sudden cardiac arrest/death. If your EF is below 35%, your doctor may talk to you about treatment with an implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy (CRT).

It's a sign of good health. But if it's too slow, it could be a symptom of a condition called bradycardia. Normally, your heart beats 60 to 100 times a minute when you're at rest. But with bradycardia, it goes down to less than 60 beats a minute.

A normal left ventricular ejection fraction (LVEF) ranges from 55% to 70%. An LVEF of 65%, for example, means that 65% of the total amount of blood in the left ventricle is pumped out with each heartbeat. Your EF can go up and down, based on your heart condition and how well your treatment works.

You should visit your doctor if your heart rate is consistently above 100 beats per minute or below 60 beats per minute (and you're not an athlete). In addition to a heart rate, you should look out for other symptoms such as: being short of breath.

Tachycardia occurs when these beat too fast. Tachycardia refers to a high resting heart rate. In general, a resting adult heart beats between 60 and 100 times per minute. When an individual has tachycardia, the upper or lower chambers of the heart beat significantly faster.

“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).

If your heart muscle has been damaged by a heart attack, heart failure, or heart valve problem, your EF may be low. A normal EF is 50-65 percent. If your EF is below 35 percent, your risk for SCA increases dramatically.

You are assessing a 440-lb man who complains of shortness of breath and lower back pain. The patient is conscious and alert, his blood pressure is 148/98 mm Hg, and his heart rate is 120 beats/min. Your MOST immediate action should be to: ... notify the receiving facility and advise them of the patient's weight and status.

The ejection fraction is usually measured only in the left ventricle (LV). The left ventricle is the heart's main pumping chamber. It pumps oxygen-rich blood up into the upward (ascending) aorta to the rest of the body. An LV ejection fraction of 55 percent or higher is considered normal.

The left ventricle is the heart's main pumping chamber. It pumps oxygen-rich blood up into the upward (ascending) aorta to the rest of the body. An LV ejection fraction of 55 percent or higher is considered normal. An LV ejection fraction of 50 percent or lower is considered reduced.

If the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs. One troublesome arrhythmia that MVP can cause is atrial fibrillation (AF).

To begin with, the female heart is somewhat smaller than a man's, about two-thirds the size. Its physiology is different, too. At puberty, the rate of repolarization or QT interval becomes longer in females and shorter in males (after age 60 those differences largely disappear).

This means that your body is working hard to ensure that your baby gets the oxygen and essential nutrients to develop healthily. If your heart beats faster but it not accompanied by other serious symptoms, there is nothing to worry about. You must remember that this is a normal physiological response of your body.

Its rate changes depending on your activity level; it is lower while you are asleep and at rest and higher while you exercise—to supply your muscles with enough freshly oxygenated blood to keep the functioning at a high level. Because your heart is also a muscle, exercise, in turn, helps keep it healthy.

Heart rates that are consistently above 100, even when the patient is sitting quietly, can sometimes be caused by an abnormal heart rhythm. A high heart rate can also mean the heart muscle is weakened by a virus or some other problem that forces it to beat more often to pump enough blood to the rest of the body.

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.
