Conclusion: Meets under certain conditions for a limited purpose. Den but satisfactory.

The manufacturer makes several references to the fact that self-diagnoses and treatments based on measurements with this equipment are dangerous. Although the evidence is not consistent, because several times by "professional use" talk, but the medical layman should take this very seriously. At best, such a single channel for the follow-up, for example, already known arrhythmias (atrial fibrillation, premature beats) can be used. But after all, this is already a significant improvement over devices that only measure the pulse wave. Especially in acute emergencies should call the emergency number and do not make self-diagnosis. Everything else is negligent.

With the cables and adhesive electrodes can be achieved quite good measurements. The quality of the analytical statements of the device is at best indicative (ASYSTOLE, Tahy (sic!), BRADY, etc.). Without knowledge of the interpretation of ECG profiles also applies here: If in doubt, ask the experts.

The measurements with hand-to-hand and hand-to-chest electrodes are unreliable and difficult to implement, since even the most minute vibrations and poor current flow through poor contact to adventurous results.

Note regarding adhesive electrodes. If Amazon can be found several electrodes that are skin-friendly and better glue than those which I got included in the set.
