Answer |
| Left vs Right bundle branch block |
"WiLLiaM MaRRoW": W pattern in V1-V2 and M pattern in V3-V6 is Left bundle block.M pattern in V1-V2 and W in V3-V6 is Right bundle block.ยท Note: consider bundle branch blocks when QRS complex is wide. |
| As a rule of thumb: A bundle branch block is indicated by what |
Widened QRS |
| Causes of ST elevation |
"Elevation" ElectrolytesLBBB, Early repolarization, Ventricular hypertrophy, Aneurysm, Treatment (eg pericardiocentesis), Injury (AMI, contusion),Osborne waves (hypothermia), Non-occlusive vasospasm |
| EKG finding of pericarditis |
*P*e*R*icardi*T*i*S*: *PR* depression in *PR*echordial leads and *ST* elevation |
| Causes of T-wave inversion |
"INVERT" Ischemia, Normality (esp in young, african american), ventricular hypertrophy, ectopic foci (calcified plaques),RBBB/LBBB, Treatments (digoxin) |
| What do elevations of V1 - V6 represent with regard to location of infarct |
"SSAALL" V1 = septal, V2=septal, V3 = anterior, V4 = anterior, V5 = Lateral, V6 = Lateral |
