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. WebLVH as a consequence of hypertension usually presents with an increase in wall thickness, with or without an increase in cavity size. Accurate assessment thus requires imaging with either echo or, even better, cardiac magnetic resonance. Various ‘voltage criteria’ seen on ECG, however, can be suggestive of LVH.

WebMar 27, 2024 · Existing ECG criteria for the diagnosis of LVH have low test sensitivities. This study suggests that a simple ECG criterion for the diagnosis of LVH (the deepest S wave plus the S wave in lead V 4 ≥2.3 mV for women and ≥2.8 mV for men) is more accurate and as specific as standard ECG criteria. WebFeb 9, 2011 · The standard speed is 25mm/sec. That means each little box is 0.04 seconds, each big box is 0.2 seconds, the whole strip is 6 seconds.
