VENTRICULAR ECTOPY
The chamber resembled a commercial airplane with 12 seats accommodating participants, a medical monitor, and a research assistant. Chamber gauges recorded humidity, temperature, noise, pressure, and carbon dioxide. Participants wore a LifeShirtData were recorded along with respiration measures, blood pressure, and pulse oximetry from peripheral devices and transmitted wirelessly for monitoring cardiac waveforms in real time. Electrocardiogram (ECG) recordings were read offline by trained technicians unaware of exposures and reviewed by cardiologists to identify supraventricular and ventricular ectopy and ECG artefacts
