Modern human life is driven by technology . We are gradually taken over by gadgets .Heart is not an exception . Implantable cardiovertor defibrillator (ICD ) is major innovation where in , an electrically wayward heart is brought under control by series of automatic shocks . One of my patients with old MI and significant LV dysfunction for whom ICD was an option taught me a lesson in physics . During counseling , he was asking me about the quality of life issues etc .
First, he wanted to know how stressful the sexual acts are ? . . .Then he surprised me with this question . He wanted to know , the risk of developing a VT/VF during the act and will the ICD shock his spouse as well ? That was a real cracker of a question I thought . I had to do a mini research and found that these are low energy shocks (30 Joules) and transmitted electrical injury is a non issue .
I realised then . . . we live in a era where physicians often get educated from their patients !
Here is the FAQs on ICD from the patient pages of circulation . With due courtesy I reproduce it here.
Final message
ICD shocks are low energy shocks delivered Intra cardiac , and rarely reach the surface , hence has little risk for electrical injury for those in contact.
