Jon-Emile S. Kenny MD [@heart_lung] Remarkably, non-invasive cardiology did not begin with ultrasound but rather as investigations into systolic time [1]. Indeed, studies on the duration of systole began in 1875 with Garrod who showed that the left ventricular ejection time [LVET] – the time that the aortic valve is open and ejecting blood – varies inversely with heart rate [
