Key result
Heat stress during exercise caused APG shape changes, including a d point depression that correlated with heart rate and core temperature, but no significant ECG changes were detected.

APG may complement ECG monitoring in exertional heat; leaves open prognostic value and clinical adoption.
Observational
A novel peak detection technique successfully analyzed ECG and APG signals during heat stress, revealing specific APG waveform changes that correlate with heart rate and core temperature.
Aya Matsuyama (2009) conducted an observational in Heat stress during exercise. Heat stress during exercise vs. Exercise in cooler conditions was evaluated on ECG and APG signal changes. Heat stress during exercise caused APG shape changes, including a d point depression that correlated with heart rate and core temperature, but no significant ECG changes were detected.
