MYOCARDIAL reperfusionARRHYTHMIAMYOCARDIAL ischemiaMYOCARDIAL injuryHEART beatRATSExercise preconditioning (EP) has a good myocardial protective effect. This study explored whether EP improves electrocardiographic (ECG) signs of myocardial ischemic/hypoxic injury and the occurrence of malignant arrhythmia after ...
When the surface of a cholesterol plaque in a coronary artery ruptures, a blood clot may form on its surface, completely blocking the flow of blood in the artery beyond the clot. The lack of oxygen immediately causes the affected heart muscle tissue to suffer (myocardial ischemia), become ir...
Every cell in the heart can act as a pacemaker. A healthy SA node has an intrinsic heartbeat generation rate of 60 to 80. If the atrium fails to generate a heartbeat, then a healthy AV node can do so at a rate of about 40, and if needed, the ventricles themselves can generate hea...
ECG is a painless test that measures the electrical activity of the heart. It can reveal several different heart problems, including ischemia, heart attacks, rhythm disorders, long-standing strain on the heart from high blood pressure, and certain valve problems. It gives clues as to the underly...
Hypercalcemia decreases the Q–T interval of the ECG and decreases myocardial function. Hypercalcemia impairs renal concentrating ability. In prolonged hypercalcemia, mineralization of soft tissue may occur. The syndrome of hypercalcemic nephropathy is well documented in animals and culminates in chronic ...

However it is important to highlight other less recognized ECG patterns suggestive of inducible myocardial ischemia during exercise stress testing which are often overlooked leading to diagnostic errors. We describe an interesting case who demonstrated transient "hyperacute" tall peaked T wave in the ...
