The influence of mobile phone electromagnetic waves on the human heart and electrocardiogram (ECG) characteristics is investigated in this comprehensive review paper, which draws insights from ten recent investigations. Concerns regarding potential health effects have developed significantly in response to the rapid proliferation of mobile phone technology and the resulting increase in exposure to radiofrequency electromagnetic waves (RF-EMW).The research examined covers a wide range of methodologies and findings. Several studies looked at the acute effects of cell phone radiation on ECG parameters, blood pressure, and sugar levels in healthy people, and found no significant changes in cardiac electrical activity, blood pressure, or sugar levels. Others investigated the effect of battery charge levels on electromagnetic wave emissions, discovering changes in power density dependent on charge levels while emphasizing the importance of the negligible impact on health.Additional research looked into the impact of extremely low-frequency pulse electromagnetic fields (ELF-PEMF)on ECG readings, which revealed minor shifts in frequency-domain signals following short-term exposure. Furthermore, studies looked into the potential impact of mobile phone radiation on heart rate variability (HRV), which suggested that using a phone increased sympathetic tone. Despite continuous discussions about the health effects of mobile phone radiation, the evidence given in these researches demonstrates that mobile phone electromagnetic waves do not significantly affect the electrical activity or ECG parameters of the human heart. The findings, however, emphasize the need for additional research to fully understand the long-term consequences of mobile phone radiation on human health, especially considering the ubiquitous usage of these devices in daily life.
