ECG changes can be caused by various factors, including ischemia (reduced blood flow to the heart), electrolyte imbalances, structural heart changes, and conduction abnormalities. Conditions such as myocardial infarction, arrhythmias, and cardiomyopathy can lead to characteristic alterations in the ECG waveform. Additionally, external factors like drug effects, stress, and metabolic disturbances may also contribute to changes in the ECG. Proper interpretation requires consideration of the clinical context and patient history.

Possible causes of a poor ECG tracing?
Causes for poor ECG tracing can be from the patient moving or interferences from electrical appliances in the room: cell phones, a lamp plug in etc
What are the effects of adrenaline on ECG?
Adrenaline increases heart rate and conduction velocity in the heart, which can lead to changes in the ECG. These changes may include a shortening of the PR interval, widening of the QRS complex, and an increase in heart rate.
How does hyperkalemia relate to the ECG?
Hyperkalemia can lead to changes in the ECG, such as peaked T waves, widened QRS complexes, and eventually sine wave patterns. These ECG changes can progress to life-threatening arrhythmias, such as ventricular tachycardia or fibrillation, which can result in cardiac arrest if not promptly treated.
What does the medical abbreviation NSST mean?
NSST on an ECG stands for non-specific ST, and is usually followed by the word "changes." Non-specific ST changes are alterations in the shape, height, or slope of the ST segment in the ECG that don't point to a particular diagnosis.
What causes sudden palpitations in heart?
There are lots of causes. You can find out by visiting a cardiologist, who can make an ECG. This will reveal any abnormalities in your heartrhythm.
Can a patient have MI without ECG changes but troponin positive after 20 hours CK was also elevated initially?
A significant portion of Acute Coronary Syndrome patients have few ECG changes. They are diagnosed based largely on positive enzymes and those aggressively treated early have much better outcomes.
