Leveraging Real Time ECG Monitoring

One of the main challenges in India is making cardiac solutions available in rural areas, which is now possible through new, portable ECG devices that run on mobile technology and use the cloud platform to transmit patient’s ECG signals instantaneously to a cardiologist.

With heart attacks being reported as the reason for the death of one Indian every 33 seconds, cardiac health has emerged as a chief concern in the country. The advancement of medical technologies has made it possible to assess the risk and take necessary preventive steps to maintain a healthy cardiovascular profile. The industry has come a long way since the time when patients had to travel long distances and wait for hours to get a doctor’s attention. Innovative advancement in communication technologies and low power circuit plan have empowered the development of better and more secure ECG equipment, which are convenient, work with lower force utilization, are more exact, and have the ability to incorporate the latest diagnostic features. Advances such as cloud storage, wireless communications, and advanced data analytics tools have enabled diagnosis even while being in remote areas.

Particularly for heart monitoring purposes, in an emergency situation, an ECG test should be done within the golden hour, but in India, it often takes about 6–8 hours. Also, more than half a million people die of heart attacks each year because of a lack of immediate medical attention. With about 70 percent of the Indian population living in rural areas, and diagnostic centers or hospitals  quite far from the places where they live,  remote monitoring devices are a necessity.

These systems facilitate the process of performing diagnosis and treatment of patients suffering from heart diseases. Using the system the physician can use the cloud platform to diagnose patients at remote locations. The patients can also access their medical records via the cloud. Paper-based reports are often at the risk of being lost or fading in the course of time. Having an affordable 12-lead ECG system on the smart phone will not only boost the digital healthcare space, but this paper-less system will save a huge amount of time, helping the patient and the doctor immensely.

Indian Market Dynamics

The ECG market has seen a major increase, and that too more in the high-end models. While the single channel, 3-channel, and 6- channel are seeing an increase in demand, it is the high-end models, which are earning the brands margins. Prices remained more or less constant. Philips, Schiller, BPL, and GE continue to be the popular brands. Edan, Mindray, Nihon Kohden, Nasan, Bionet, Silverline Meditech, Krishna Medi, Nidek, Skanray, Maestros, and RMS too have presence in the market. Building a strong and equitable healthcare system is an important landmark in a developing country’s journey. That can happen only if quality healthcare is provided to large segments of the population, which today is not the case in India. In 2016, heart diseases were the biggest killer, accounting for 28.1 percent of all deaths in India, according to the Indian Council of Medical Research, the Public Health Foundation of India, and the Institute for Health Metrics and Evaluation. While heart attacks can be detected by a quick ECG test, the country continues to be a victim of two critical issues, that is, most primary care clinics are not equipped with ECG machines and absence of sufficient training.

According to DRG’s Ambulatory ECG Monitoring Devices report, the revenue earned by monitoring companies was over a billion dollars in the US of America in 2016 and growing in double digits for the next few years. While in India, the market (although smaller) is expected to grow at an even higher rate. Healthcare startups are mushrooming in this high-growth space and are trying to deploy solutions that will transform the market.

Not only is SanketLife able to perform a single-lead ECG reading for emergency purposes, like AliveCor’s popular Kardia Mobile ECG monitor, but also has built-in provision to take 12-lead readings just as a conventional ECG machine, which makes it a complete 12-lead ECG solution that is remote, easy-to-handle, cost-effective, without any lead or wire, and accurate. The technology allows it to measure electrical activity of the heart through sensors and to transfer the data to a mobile phone using low-energy Bluetooth technology that can be shared with anyone for consultation over the cloud network

A tele-ECG machine prototype developed by Bhabha Atomic Research Centre (BARC) is being adopted by firms to offer healthcare solutions even for remote areas. Scientists at BARC recently developed the handheld 12-channel tele-ECG device that promises cardiac care at just a click. The prototype is developed to record all the 12-leads of ECG simultaneously and displays the same on mobile screens. The generated report can be immediately shared with experts via mobile phones’ Multimedia Messaging Service (MMS) or any other file sharing apps, thus saving on the time it takes to transport patients from their location to the nearest available cardiac units

Uber Diagnostics’ Cardiotrack is a handheld ECG monitor that is easy to use, provides clinical grade output, and performs predictive diagnosis to start intervention immediately, thus reducing the need for invasive intervention. It is a network-connected device; wherein a patient’s ECG scan can be instantaneously transmitted to a cardiologist anywhere in the world. Cardiotrack allows doctors to take a 12-point ECG from a patient. It can then be transferred to a smartphone or tablet via Bluetooth and, from there, can be uploaded to the cloud. It also raises an alarm if it detects an irregularity during the test

Tricog, a Bangalore-based start-up, has partnered with GE Healthcare to develop cloud-connected ECG devices that are placed at under-served locations to help doctors detect heart complications. Within minutes of an ECG test, cardiologists at Tricog’s center complete the diagnosis and share the interpretation with both the patient and the local doctor in real time. The system is designed to additionally enable continuity of care at a tertiary center through timely referral. Patients can also see their records and show them to doctors in future

Another firm, Cardiac Design Labs, has also built a similar product like Tricog, which is a low-cost, wearable cardiac monitor, Mircam. The product aids in initial diagnosis and sends alerts to doctors

A clutch of global tech companies are also demonstrating how designing products specifically for India can help crack the Indian market – and make innovative products for the world. Medical device manufacturing giants such as Johnson & Johnson, GE, and Philips have designed and developed Made in India Med-Tech products best suited for local Indian market needs. It is no surprise that GE wants to set up its largest digital hub in India. The company has also introduced an electrocardiogram (EKG) system that is priced 80 percent lower than a similar imported product available in India. Companies including AliveCor, available in India through the Apollo Group of Hospitals; Kito+, a smartphone case run by San Francisco-based company Azio, which also works as a fitness tracker and can even conduct an ECG, can also be seen in the Indian market.
