Checkme Portable ECG/EKG Monitor with Touch Screen, Handheld Heart Rate Tracking Device, Free App for iOS and Android, Blue Heart Monitor with Pulsebit EX

Great value for money! Great for sharing with a doctor in case your heart is playing up but never when you visit the doctor. Do not forget to buy spare electrodes - you will run out quickly even if they are reusable. HAND MODE (No electrode): This is great for a quick check if your pulse is regular and check bpm and see if you see arrhythmias like PAC, PJC or PVC. CABLES MODE (With electrodes): Your output will be much much smoother and it gives more information on durations of waves, amplitude, see if there are any U waves and so on. As it can be seen from the attached photos it is not easy to correctly pick the Isoelectric line. This is not the fault of the unit it is simply better to check (if needed) with proper ECG machine and see all 12 leads. In my case, I was able to resolve and improve my ECG with magnesium intake (it was measured 0.86 = OK but at a lower threshold). And some bananas, avocados (potassium increase by food). My two boys (17 and 14) also appreciated some learnings about P, QRS,T,U waves and how it relates to hear electric control and muscular function. How myocardial muscles compress using N+,K+,Ca+. Importance of Mg and other minerals. They started to eat more vegetables after some education :) I highly recommend this product. But see your doctor if in doubt. Better be over careful than sorry. Software Bluetooth is very good. Desctop I wish there would be a crosshair mouse tracker. Photos comments: 1 - You can see T wave not repolarizing on downhill well. This has improved with magnesium and food potassium increase diet. 2 - Not easy to pick zero line. Zero line was 0.05mV different prior P wave vs PQ segment. 3 - Example of low-quality readings of you moving too much or electrodes are old (after 25 uses or so see the recommendation of Wellue). 4 - It picks PAC very well 5 - Regular rhythm
