Case Example Of An ICD Shock During A Celebration
- A 67‑year‑old man with cardiac sarcoid and prior VT had an ICD shock while celebrating his grandson's birthday but felt well afterward.
- Charlie Wiener and Cathy Handy Marshall use this case to explore post‑shock management.
ICD Shock Warrants Cardiac Reassessment
- An ICD shock often signals possible worsening cardiac status and mandates evaluation rather than dismissal as an isolated event.
- Cathy Handy Marshall emphasizes device interrogation to confirm VT therapy and reassess cardiac function after a shock.
How Patients Should Respond After An ICD Shock
- Do use remote monitoring or wait until the next working day after a single shock if asymptomatic, but seek immediate care for multiple shocks or concerning symptoms.
- Cathy Handy Marshall advises against driving to the hospital after an ICD shock.
