Summary
Cardiac resynchronization therapy can be complicated by Twiddler syndrome, where device leads move. This case shows lead dislodgement causing atrial sensing issues and inappropriate shocks in a patient.
Area of Science:
- Cardiology
- Medical Devices
Background:
- Cardiac resynchronization therapy (CRT) is a treatment for heart failure.
- Device-related complications can impact CRT efficacy.
Purpose of the Study:
- To report a case of Twiddler syndrome complicating CRT.
- To highlight the diagnostic and management challenges.
Main Methods:
- Case report of a patient with CRT.
- Review of device interrogation and imaging findings.
Main Results:
- The patient developed Twiddler syndrome with lead migration.
- This resulted in triple atrial sensing and inappropriate shocks.
Conclusions:
- Twiddler syndrome is a potential complication of CRT.
- Awareness is crucial for prompt diagnosis and management to prevent adverse events.

430
Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

01:30Pulse rhythm
1.2K
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

01:19Electrophysiology of Normal Cardiac Rhythm
8.5K
The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase...
