General Information

  • What is an ECG/EKG?
    An electrocardiogram (ECG or EKG) is a simple, non-invasive, and painless test that records the electrical activity in your heart. ECGs are used to check for signs of heart disease.
  • What is the difference between a single lead (1-lead) and a 12-lead ECG?
    A single-lead ECG is used for arrhythmia detection and basic heart monitoring. A 12-lead ECG is used to provide a comprehensive view of the heart and is the medical standard for screening and diagnosing various heart conditions. A 12-lead ECG is often used to detect or diagnose arrhythmias, heart attacks, drug effects on the heart, and many other heart diseases.
  • What is PCA 500?
    PCA 500 is the first and only FDA-cleared, hospital quality 12-lead electrocardiogram (ECG) for professional and personal use.

  • For whom is PCA 500 appropriate?
    PCA 500 is intended for the millions of people who suffer from chronic heart disease. PCA 500 is mostly used for quick and accurate clarification of unclear symptoms and for the prevention of life-threatening events. For patients who just had surgery, a stent placed, or an ablation procedure, PCA 500 may be useful for follow up and detecting changes. It is also designed for home use by patients with chronic heart failure and arrhythmias. PCA 500 also has applications in preventive medicine.

  • What should I do when a lead-off warning is shown?
    Tap on the yellow question mark icon in the top right corner. Check the corresponding chest electrode(s). Make sure each electrode is attached properly to the skin and making a good physical contact. Ensure there is no hair or oil interfering with skin contact. If needed, shave the chest hair under the electrode strip or wipe off excess oil with a moist cloth. Firmly press on the area of the strip indicated in yellow to ensure good electrode contact with the skin. In a low humidity environment, electrodes may dry up, preventing adhesion to the skin. If the electrodes have been stored in a dry environment, and a "lead-off" alert is shown in the app during use, please use a moist cloth to dampen the patient's chest and reattach the electrode.
