All ECGs are not created equal. Apple’s recently unveiled 1-lead ECG on its Series 4 Apple Watch is a great advance in screening one’s heart activity beyond a mere pulse reader. It offers the capability to detect potential arrhythmias. However, medical professionals require more to make a diagnosis. CardioSecur, a mobile, app-based, 15-lead ECG system for private use fills this gap. Its direct in-app feedback - if medical attention is needed - offers additional clarity and peace of mind anytime, anywhere.
