What does a slurred S wave mean?
What does a slurred S wave mean?
This produces a secondary R wave (R’) in the precordial leads, and a wide, slurred S wave in lateral leads. Normal activation of the left ventricle means that cardiac axis remains normal in isolated RBBB.
Why does RBBB cause right axis deviation?
Right bundle branch block does not alter the electrical axis of the heart. Axis deviation indicates that there is concomitant fascicular block. Left axis deviation suggests concomitant left anterior fascicular block. Right axis deviation suggests concomitant left posterior fascicular block.
Can RBBB cause stroke?
RBBB in the Framingham study has been associated with (but not caused by) atrial fibrillation, atrial premature contractions, elevated cholesterol, diabetes, stroke, transient ischemic attacks, smoking, obesity, and hypertension.
What is sinus rhythm with right bundle branch block?
Right bundle branch block is an obstacle in your right bundle branch that makes your heartbeat signal late and out of sync with the left bundle branch, creating an irregular heartbeat. Electrical signals in your heart act like a pacemaker that controls your heartbeats.
Is T wave inversion normal in Rbbb?
Remember that T wave inversions and ST segment depression are normal in leads V1 to V3 in the presence of a right bundle branch block; thus, myocardial ischemia technically cannot be easily determined in these leads.
What does Rbbb look like on EKG?
The characteristic ECG findings for right bundle branch block are as follows: QRS duration is greater than or equal to 120 milliseconds. In lead V1 and V2, there is an RSR` in leads V1 and V2. In Leads 1 and V6, the S wave is of greater duration than the R wave, or the S wave is greater than 40 milliseconds.
Can RBBB cause hypotension?
RBBB can be chronic and lifelong; it can also be intermittent. In some people it is related to heart rate. It is possible to have a low blood pressure caused by dehydration.
