The jolt restarted his heart and paramedics took him to hospital

The jolt from being stomped on? I didn't know CPR could restart someone's heart.

Most things that require CPR *aren't* stopped hearts: Heart Attacks are generally fibrillation (arhytmic spasming/the rhythm getting farked) than utterly stopped.

CPR (or jolts) can force the heart back into regular rhythm.

Unless it's on a pediatric or infant with bradycardia and signs of hemodynamic collapse, every person getting CPR is because they show signs of questionable life status (layperson), or they have no pulsatile heart rhythm (Healthcare Provider).

A heart attack is NOT an arrythmia. A heart attack is caused by a section of the coronary artery either becoming obstructed or spasming/constricting - or if systemic blood pressure drops too low, not being perfused adequately so that the tissue becomes ischemic or starved of oxygen and nutrients.

Fibrillation is a result of ischemic or irritated cardiac tissue producing an ectopic beat at just the right point on the cardiac cycle to cause the heart to quiver uncontrollably.

Ventricular fibrillation can occur from a heart attack or cardiac ischemia, but there are other causes, such as channelopathies, trauma, and generalized ischemia. They are, however, the most common lethal arrythmia that people who have heart attacks develop. Ventricular Tachycardia can also develop if certain cardiac conduction channels are damaged as a result of that ischemia/infarction. (A myocardial infarction is a heart attack). In fact, lethal arrythmia is the most common cause of death within 8 hours of a heart attack.

CPR does not jolt the heart back into rhythm. It manually compresses the heart and increases intrathoracic pressure to produce a cardiac ejection and refilling. It buys time to defibrillation in the case of ventricular tachycardia or fibrillation and circulates medicine to the heart, or buys time to correct the underlying cause of asystole or pulseless electrical activity by perfusing the myocardium and other organs, but only provides 33% of the necessary cardiac output for life.

For every minute that defibrillation is delayed with CPR, the chance of neurologically intact discharge drops 10%.

We call it a chain of survival for a reason. Sudden Cardiac Arrest survival depends on every link in that chain.
