Recently purchased SonoHealth EKG to record my EKG and Blood pressure to provide to my Doctor. My blood pressure had some usual spikes we wanted a record based over a three month period to monitor what was happening. Although the doctor did not request the EKG, I found the SonoHealth unit realized that providing a copy of my EKG, along with taking my Blood Pressure with my wrist cuff unit, and entering it on my EKG report, would give my Doctor a more comprehensive view of what was going on. The SonoHealth EKG unit is a well made and designed, quality unit. The design is well thought out and easy to use. Being able to record the EKG results to my computer and I-Phone is easy and a big plus. Additionally, the total cost for all services is in the base purchase price. I checked on some other brands and found additional subscription costs each month were involved. Not so with SonoHealth. I would recommend purchase to any of my friends. Jim Cavender
