Temperature‐Dependent Modulation of the QRS Axis Following Water Intake in Healthy Adults: A Cross‐Sectional Study
ABSTRACT Background and Aims Anecdotal concerns persist regarding the safety of cold and warm water ingestion and their impact on cardiac rhythms. This study aimed to investigate the acute effects of water temperature on QRS amplitude, duration, and axis in healthy individuals using electrocardiography (ECG). Methods A cross‐sectional study was conducted between January 2019 and October 2020 with 25 healthy volunteers (aged 18–35). Participanats ingested 250 mL of cold (0°C–8°C), room‐temperature (~27°C), and warm …
