Key result
IoT-based ECG system transmits real-time cardiac signals to a cloud platform with ~1 second latency.
Why the study?
Conventional ECG monitoring requires observation in hospitals or clinics, limiting accessibility and continuous monitoring needed for timely diagnosis of cardiovascular diseases.
A low-cost IoT-based ECG monitoring system using an AD8232 sensor and ESP32 microcontroller successfully demonstrated real-time cardiac signal acquisition and cloud transmission.

Patel et al. (2025) studied Cardiovascular diseases. IoT-based ECG monitoring system (AD8232 sensor and NodeMCU ESP8266) was evaluated on System performance (signal accuracy, latency, power consumption). The developed IoT-based ECG monitoring system successfully acquired and transmitted real-time cardiac signals to a cloud platform with 0.8-1.2 seconds latency and a 360 Hz sampling frequency.
