Review on 📈 SonoHealth Portable EKG Heart Rate Monitor - Wireless Handheld Home ECG Cardio & Electrocardiogram Machine with Biofeedback Finger & Chest Leads - View Irregular Cardiac Arrhythmia Vitals on Mobile Phone by Paul Giordano

Company has no phone number to contact, has never responded to support messages. The device picks up a lot of noise and the readings are not accurate at all. With this device you can take a decent single lead EKG recording and view the recording in the dedicated smartphone application. However, recordings tend to be very noisy and full of artifacts, making it difficult to discern the rhythm. There is no corresponding filtering in the software.
