Essentials in looking at an ECG
Rate, Atrial and ventricular rates.
QRS axis, T axis, QRS-T angle
Intervals: PR. QRS, and QT
P wave amplitude and duration
QRS amplitude and R/S ratio
St- Segment and T wave abnormalities
Inverted (or negative) T waves can be a sign of
Formed by the QRS axis and the T axis
QRS-T angle >60 degrees is unusual but if > 90 degrees, it is abnormal.
Abnormally wide angle, with T axis outside the normal quadrant is seen in
- severe ventricular hypertrophy with starin
- Ventricular conduction disturbances
- Myocardial dysfunction of a metabolic or ischemic nature.
premonitory signs and symptoms of imminent syncope occur; dizziness with or without blackout, pallor, diaphoresis, thready pulse and low BP
Absent or inadequate upright position response, Hypotension without increased HR
Examination, CXR, ECG, Echo
