WebTypes of ST segment elevations on ECG. Current guideline criteria for ischemic ST segment elevation: New ST segment elevations in at least two anatomically contiguous leads: • Men age ≥40 years: ≥2 mm in V2-V3 and ≥1 mm in all other leads. • Men age <40 years: ≥2,5 mm in V2-V3 and ≥1 mm in all other leads. WebThe ECG machine processes the signals picked up from the skin by electrodes and produces a graphic representation of the electrical activity of the patient's heart. The basic pattern of the ECG is logical: electrical activity towards a lead causes an upward deflection. electrical activity away from a lead causes a downward deflection.

WebAn electrocardiogram (ECG or EKG) is a test that checks how your heart is functioning by measuring the electrical activity of the heart. With each heart beat, an electrical impulse (or wave) travels through your heart. This wave causes the muscle to squeeze and pump blood from the heart. An ECG measures and records the electrical activity that ...
