How To Calculate Target Heart Rate After A Heart Attack
On stress test: Target heart rate is defined as 86% of maximal predicted heart rate. Mphr = 220-age in years. ...Read more
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
Target Heart Rate:
Your maximum heart rate is 220 - age.
Your training heart rate range is classically spoken of as between 60-80% of your maximum. ...Read more
Can you tell me what you suggest if the resting heart rate is 72, calculate this persons target heart rate and vo2 at 60% of maximum?
90- 153: Remember it is just a target heart rate to get to during exercise, and not a number to get fixated to as you can see this is quite a wide range maximum heart rate in 40 year old is 180. The benefit you get from exercise is not so specific at particular rate so do not worry to much about the rate just keep regular exercise schedule and follow it good luck. ...Read more
Resting HR: A target resting heart rate for you should be between 60-80. ...Read more
The target heart rate (thr) is usually 50-75 % of the maximum heart rate for an individual.
Ideally you get the maximum benefit when you stay with in the thr but going over for a few minutes is not a big problem.
There really is not major advantage from a training perspective to go above the thr. ...Read more
Nothing: When people ask me about what their target hr should be when working out, I tell them that the workout intensity is more important than heart rate. So if you feel like you are overdoing it, are exhausted and feeling sick after your workout, and your hr was less than target, it was too much. Decrease intensity. If hr is higher than target, and you feel ok afterwards, that's ok, no problem. ...Read more
Doesn't change: Resting heart rate has no bearing on target heart rate. Your age predicted maximal heart rate (apmhr) is 220 - age. Target heart rate is a % of that. Typical for exercise is 70-85% of apmhr. ...Read more
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
Not necessarily: Consistently dong exercise above your thr rate means you may bumping up against your maximal health rate. The thr is a safe and good level to exercise at without any risk to your heart. ...Read more
Weed: Heart attack is a multifactorial event. If weed was a common cause of heart attack, Bill Maher probably wouldn't be pushing it to be legalized. ...Read more
My heart rate is usually 60-70 today it's been between 90-100 why? Could this be a sign of heart attack
Not if no other symp: It is not likely to be a heart attack without other symptoms like chest pain, shortness of breath, palpitation or dizziness. Just an elevated HR is more likely to be reasons other than the heart, ie. dehydration, anxiety, deconditioning, pain, fever, anemia, etc. Check out Your Vibrant Heart on Amazon for more cardiac health tips. ...Read more
My heart rate is 120 but I haven't done anything but shower this morning. Even when I sit down it feels fast. I'm only 17 & scared of heart attack?

Not usual but it can: The fast heart beat which is generated by the lower heart chambers (ventricular tachycardia) can reduce the blood volume generated by the heart and if the subject has low preserve (some narrowing of the coronary arteries or decreased heart function) can cause ischemia t the heart. ...Read more
No: There is no such thing as "target heart rate." depending on your training goals, the "target" could be anything from 60% to 100% of your max heart rate. Exceeding ~80-84% of max heart rate shifts metabolism to anaerobic (airless) metabolism resulting in the production of Lactic Acid and the burning sensation. The body is burning pure glucose here. Muscles break from overuse, not that process. ...Read more
Not necessary: I assume you are talking abou your maximum calculated hr. If that's the case, not necessary. Depend how long you stay there. With high protein diet, weight lifting and short burst 1-2 mins every 5 mins of fast running for no more than 30mins, 3 times a week, probably not. Every person is different but you will built endurance and cardiac capacity. Check with a trainer for better results. ...Read more
First calculate: Your maximal heart rate by using 220-age if male and 207- (age x 0.88) if female. Then, during aerobic exercise, you will try to reach 60-70% of the mhr and stay for as much as you can. I always advise for a medical exam before starting any conditioning exercises. Have fun. ...Read more
Target heart rate: Depends on the purpose of the target rate. Usually this is a good thing that is helping one get fit. ...Read more
