How high does your heart rate need to be before you get a heart attack?

Not related: A heart attack can occur at any heart rate if there is a blood clot in the artery or a blockage. If there is a severe narrowing than a higher heart rate will increase the risk of a heart attack as the demand of a higher heart rate would out strip the supply. ...Read more

Myocardial Infarction (Definition)

Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & ...Read more

How high does your heart rate need to be to have a heart attack?

How high does your heart rate need to be to have a heart attack?

No simple answer: If your arteries have no blockage, then there is no heart rate that will cause a heart attack. The more blocked the arteries, the lower the hr needed to outstrip the blood supply. There are other factors too, like presence/absence of anemia, hypertension, left ventricular hypertrophy, (wall thickening), and contractility which determine how much blood the heart is using and needs. ...Read more

How low would your blood pressure need to get to cause a heart attack or stroke?

How low would your blood pressure need to get to cause a heart attack or stroke?

It can happen: Blood pressure is an element and the very high can tear the aorta or the coronaries, but blockage by plaque and clot occurs with or without BP elevation. The very low- shock can cause low coronary or brain blood flow. Generally less than 70-80 mm hg is a concern. Brain maintains good auto regulation from about 60 -160 if there is not other blockage or micro vessel disease. ...Read more

How slow does your heart rate have to be for a cardiac ct scan?

How slow does your heart rate have to be for a cardiac ct scan?

It depends on the: scanner. If it is 64 slice scanner, HR should be 65 or less. The slower the heart rate, the better the pictures. Docs use beta blocker meds to decrease the heart rate. I give 25-100 mg as needed. If someone's HR is over 90 before going for scan (before the meds), it can be hard to get HR down. If it is a high speed scanner, HR could be faster.

Can exercise have to get your heart racing to be good?

Can exercise have to get your heart racing to be good?

Exercise: Productive exercise causes the body to need more blood flow to the tissues to cause induction of increased exercise capacity. An increased heart rate during exercise indicates this is in play. In general if the exercise isn't enough to elevate heart rate, it isn't enough exercise. The heart rate target is usually 120 to 150 but higher rates are appropriate for some people. ...Read more

Can you still have a heart attack or go into cardiac arrest if you have a pacemaker?

Can you still have a heart attack or go into cardiac arrest if you have a pacemaker?

Yes: Both of these problems are due to issues not addressed by the pacemaker. A heart attack is generally due to a blockage and a heart artery, and cardiac arrest is usually due to an exceedingly fast heart rate where the pacemaker only fixes slow heart rates. A defibrillator is the device of choice to treat cardiac arrest. ...Read more
