What causes ecg changes?
Can a patient have MI without ECG changes but troponin positive after 20 hours CK was also elevated initially?
ECG gives information about the rate, rhythm, and information about conduction of nerve impulses in the heart, evidence of damage to the heart from poor blood supply or previous heart attack, and of course changes to suggest recent heart attack. It is therefore useful to diagnose atrial flutter, fibrillation, heart block, ischaemic changes and heart attack
Describe the changes that take place when a match burns Are these changes physical or chemical changes?
Poor R-wave progression is a common ECG finding that is often inconclusively interpreted as suggestive, but not diagnostic, of anterior myocardial infarction (AMI). Recent studies have shown that poor R-wave progression has the following four distinct major causes: AMI, left ventricular hypertrophy, right ventricular hypertrophy, and a variant of normal with diminished anterior forces. Standard ECG criteria that identify and distinguish these causes have been developed. An interpretive approach to the ECG with poor R-wave…
