What does a normal nuclear stress test mean?

Normal Results A normal test most often means that you were able to exercise as long as or longer than most people of your age and sex. You also did not have symptoms or changes in blood pressure, your ECG or the images of your heart that caused concern.

Can stress cause high troponin levels?

Stress-induced cardiomyopathy mimics symptoms of acute myocardial infarction with acute chest pain, electrocardiographic changes and a transient increase in the level of cardiac biomarkers including troponins.

What should I avoid after a nuclear stress test?

Caffeine can alter the test results. Do not eat chocolate or drink coffee, tea, soda, colas or other caffeinated beverages such Mountain Dew or energy drinks. If you are unsure, do not drink it.

Can high blood pressure cause elevated troponin?

Troponin levels may remain high for 1 to 2 weeks after a heart attack. Increased troponin levels may also be due to: Abnormally fast heartbeat. High blood pressure in lung arteries ( pulmonary hypertension )

How fast does your heart beat during a stress test?

Your target heart rate during a stress test depends on your age. For adults, the maximum predicted heart rate is 220 minus your age. So, if you’re 40 years old, the maximum predicted heart rate is 220 – 40 = 180.

Do troponin levels return normal?

Troponin levels typically start to elevate in the circulation within 2 to 3 hours of the onset of chest pain. The levels will continue to rise at that time until a peak is reached, generally between 12 and 48 hours. The troponin level will then begin to fall over the next 4 to 10 days down to a normal level.

How long does troponin stay in the blood?

Levels of troponin can become elevated in the blood within 3 to 6 hours after heart injury and may remain elevated for 10 to 14 days. Increased troponin levels are not be used by themselves to diagnose or rule out a heart attack. A physical exam, clinical history, and ECG are also important.

How long does it take for troponin to return to normal?

Is a heart rate greater than 200 beats per minute bad?

An exercise heart rate greater than 200 beats per minute is likely doing you and your heart more harm than good, and it may even be putting your overall health at risk. Safe and beneficial aerobic exercise is that which elevates your heart rate to a number of beats per minute that falls within your THR, or target heart rate, zone.

Is it dangerous to have a resting heart rate of 120?

Yes, especially if it’s a resting heart rate, anything over 120 beats at a resting rate is dangerous and classed as Tachycardia – bradycardia means it beats below 60 and you’re not a trained athlete who sometimes have one as low as 40 – seriously see your GP/doctor or whatever medical professional you have…

What does it mean when your heart rate is less than 60?

Bradycardia is typically defined as a heart rate that’s less than 60 beats per minute. For athletes and people that exercise regularly, a heart rate of under 60 beats per minute is normal and even healthy. Some possible causes of bradycardia include: side effects from medications

Is it possible to have a heart rate of 300?

Nevertheless there have been numerous cases in the literature which have actually reported the heart rates of above 300 per minute. The fastest human ventricular conduction rate reported to this day is a performed tachyarrhythmia with ventricular rate of 480 beats per minute.
