irregular heart rhythm

A heart arrhythmia (uh-RITH-me-uh) is an irregular heartbeat. Heart rhythm problems (heart arrhythmias) occur when the electrical signals that coordinate the heart's beats don't work properly.

What causes the sudden death of about 50% of heart failure patients?

Introduction. Cardiac arrest is the mode of demise in 30–50% of patients with heart failure and a reduced ejection fraction (HFrEF), and conversely, systolic dysfunction is a major risk factor for sudden cardiac death in the community.

Can someone with heart failure die suddenly?

What causes sudden cardiac death in early morning?

Unlike heart attacks (myocardial infarctions), which are typically caused by clogged coronary arteries reducing blood flow to the heart muscle, sudden cardiac arrest is the result of defective electrical activity of the heart. Patients may have little or no warning, and the disorder usually causes instantaneous death.

Is dying from congestive heart failure painful?

Some people with heart failure can experience pain or discomfort towards the end of their life. They should be assessed using a pain scale.
