An electrocardiographic finding in which there are two R waves, which are two deflections above the baseline resulting from a single ventricular … WebThe ECG is characterized by deep and persistent, concave-upward ST-segment depression in multiple limb and chest leads. ECG changes are stable over time and accentuated during exercise. Patients present with syncopal episodes, ventricular tachycardia (including torsade de pointes ), ventricular fibrillation and sudden cardiac arrest.

As mentioned above, most of the time an ECG reader mentions an rSR’ pattern on the ECG, the QRS complex is narrow or only mildly prolonged. A majority of the time this finding is a benign finding from abnormally high lead placement of V1 and V2, a normal variant seen due to normal depolarization of the … See more Not to belittle anyone, but to understand what an rSR’ is, we first need to know the components of the QRS complex. 1. Q-wave: The first downward deflection before the R-wave 2. R-wave:The first upward deflection of … See more Now that we know the parts of the QRS complex, an rSR’ is simple. It is an R-wave, followed by an S-wave, followed by another R-wave. In other words, an upward deflection, followed by a downward deflection, followed … See more An rSR’ in V1 or V2 in a widened QRS complex is abnormal. This may be due to a right bundle branch block (RBBB), preexcitation or Wolff … See more As you may have guessed by now, most of the time, and rSR’ is a benign finding. It is often from lead misplacement, is a normal variant, or may indicate a slight right ventricular conduction … See more WebAn axis of 90 ° to 180 ° is considered right axis deviation; it occurs in any condition that increases pulmonary pressures and causes right ventricular hypertrophy (cor pulmonale, … synonyms for apex predator
