As well as no p waves, ... thus the tall R waves are the opposite of Q waves (remember Q waves are negative), and ST depression occurs in place of ST elevation. However, a falsely “new” IRBBB might prompt the unwary clinician to consider pulmonary embolism, among other diagnoses. What could this mean? LehmannImportance … May resolve in days or weeks or persist indefinitely. And one does not typically see a nearly identical appearance in V1 and V2, with negative P waves and T inversion that also looks nearly identical to what we see in lead aVR in ECG #2, once the limb leads were correctly placed. In some cases, the rSr’ or qR pattern may combine with a mild degree of benign anterior ST segment elevation (aka “male pattern”). It may be noted that initial part of P wave is contributed by right atrium as it is activated first and the second part by left atrium which is activated later. Follow - 1.
