The CardiacSense watch can catch palpitations which could otherwise be missed

Often, when patients arrive at the emergency department with complaints of heart palpitations or chest pressure, their symptoms have already reduced in severity or have resolved themselves1. In addition, due to the heavy demand for specialists, the patient often cannot see a cardiologist for a couple of weeks or even months. The original symptoms have, meanwhile, disappeared or only appear sporadically in between appointments. These sensations are difficult to predict so continuous measurement, offsite monitoring, and responsive alerts are the only ways to catch these symptoms when they happen.
  • Heart palpitations are often transitory and difficult to diagnose
  • Common intermittent monitoring solutions can miss these events as they are sporadic
  • Around 1 in 10 people report palpitations to their physician2

Twelve-lead electrocardiograms (ECGs) are one of the most frequent ways to assess cardiac health and are available in many clinics or hospitals. However, these require the patient to be on-site or for a physician to be present when using the device. This means that only palpitations that occur during medical visits are caught, and those that occur in between visits are missed.

The CardiacSense watch uses both a one-lead ECG (measuring electrical signals in the heart) and a photoplethysmography (PPG) sensor (measuring the rate of blood flow through light-based technology) to give a comprehensive overview of a patient’s cardiac health. This medical device is worn like a smartwatch and can be worn by the patient going about their daily lives. When compared to an FDA-approved ECG Holter, the CardiacSense watch showed a sensitivity rate of no less than 96%3 . Classic smartwatches that provide heart monitoring services rely on intermittent measurements rather than continuous ones, so there are large gaps in the data they provide4.

In case of deterioration of the patient’s health, the healthcare provider will be alerted, and the patient can be called for consultation. In addition, once the patient does see a specialist or physician, they will have a wealth of intermediate recorded data to inform the healthcare practitioner’s decisions.
