In patients with stable coronary heart disease (CHD) up to 70% [1] Mental stress-induced myocardial ischemia (MSIMI) is a medical condition in which acute psychological stress can trigger a transient myocardial ischemia , which is a state of reduced blood flow to the heart muscle , often without the presence of significant coronary artery ...
Theories suggest a link between brain activation of stress-related biochemicals (including neuropeptides) and the effects these chemicals have on areas of the heart, especially neuropeptide Y. [27] More specifically, adrenal stimulation by the sympathetic nervous system has been noted in cases ranging from physical events such as ischemic ...
A resting heart rate of 100 beats per minute or an increase in heart rate of 100 beats per minute with minimal exertion; Excluding any potential secondary causes of sinus tachycardia; Ruling out atrial tachycardias; Palpitations or presyncope (or both) symptoms that have been clearly linked to resting or easily induced sinus tachycardia.
“More women than men die of heart disease every year, yet women have a 59 per cent increased risk of being misdiagnosed with acid reflux, stress, or anxiety,” Dr Nance said.
Normal heart rate varies based on a person’s age, fitness and activity levels, temperature, caffeine, stress, and other risk factors (such as blood pressure, chronic diabetes, obesity, etc ...

Normal heart rates vary with age and level of fitness, from infants having faster heart rates (110-150 bpm) and the elderly having slower heart rates. [3] Sinus tachycardia is a normal response to physical exercise or other stress, when the heart rate increases to meet the body's higher demand for energy and oxygen, but sinus tachycardia can ...
