Cushing reflex (also referred to as the vasopressor response, the Cushing effect, the Cushing reaction, the Cushing phenomenon, the Cushing response, or Cushing's Law) is a physiological nervous system response to increased intracranial pressure (ICP) that results in Cushing's triad of increased blood pressure, irregular breathing, and bradycardia.

Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block.
Myocardial infarction; Other names: Acute myocardial infarction (AMI), heart attack: A myocardial infarction occurs when an atherosclerotic plaque slowly builds up in the inner lining of a coronary artery and then suddenly ruptures, causing catastrophic thrombus formation, totally occluding the artery and preventing blood flow downstream to the heart muscle.
Hospital cases at new high as health chiefs raise fears that those with symptoms are failing to seek help
The Seven Countries Study suggested that the risk and rates of heart attack and stroke (CVR), both at the population level and at the individual level, correlated directly and independently to the level of total serum cholesterol, in seven sampled out countries. It demonstrated that the correlation between blood cholesterol level and coronary ...
This is a list of countries ranked by the quality of healthcare, as published by the Organisation for Economic Co-operation and Development (). [1] The ranking takes into account various health outcomes, including survival rates for seven types of cancer, as well as for strokes and heart attacks.
Often sinus node dysfunction produces no symptoms, especially early in the disease course. Signs and symptoms usually appear in more advanced disease and more than 50% of patients will present with syncope or transient near-fainting spells as well as bradycardias that are accompanied by rapid heart rhythms, referred to as tachycardia-bradycardia syndrome [4] [5] Other presenting signs or ...
Ictal bradycardia is when people with temporal lobe epilepsy experience bradycardia with their seizures (epileptic discharges). Bradycardia is defined by a slower than normal heart rate, less than 60 bpm. (Normal range is 60-100 bpm). Ictal epileptic discharges can effect changes in cardiac rhythm. An increase in heart rhythm is common during ...
