(FIT)-Module 5 Workshop 8: Device Cases-Asirvatham Case 1 Answer

Video Transcription

Video Summary

In this video, the speaker discusses possible reasons for a patient's failure to respond to cardiac resynchronization therapy (CRT). They mention that there could be an issue with the left ventricular lead or an offset. Frequent premature ventricular contractions (PVCs) could also be minimizing the effectiveness of the CRT system. The speaker notes that the patient may have had a CRT system placed without an atrial lead, which can result in a loss of atrioventricular (AV) synchrony, diminishing the benefits of ventricular synchronization. Overall, the video highlights the importance of evaluating the 12-lead electrocardiogram (ECG) to troubleshoot CRT failure.
