Electromagnetic energy radiated from mobile phone alters electrocardiographic records of patients with ischemic heart disease.
This study assessed whether mobile phone radiofrequency exposure during a 40-second ringing period alters ECG parameters in 356 participants across cardiac disease groups, with gender stratification. The authors report QTc prolongation in males across groups, including males with ischemic heart disease, and additional voltage-criteria changes in males with ischemic heart disease. Female patients with ischemic heart disease did not show these reported changes, and phone placement (belt vs precordium) was reported to influence effects.
Key points
- The study compared ECG recordings with a mobile phone turned off (baseline) versus turned on for 40 seconds of ringing.
- Participants (n=356) were grouped into no cardiac disease, ischemic heart disease, and non-ischemic cardiac disease history.
- QTc prolongation was reported in males in the no-disease and non-ischemic cardiac groups during exposure.
- Males with ischemic heart disease showed reported QTc prolongation and changes in ECG voltage criteria during exposure.
- Female patients with ischemic heart disease did not show the reported ECG changes.
- Phone position (belt level vs over the precordium) was reported to affect the heart/ECG outcomes.
