On a sullen day in August, Hyderabad-based entrepreneur Priya (34) sensed her heart violently pounding in her chest. “It felt like I was running a marathon while sitting on the sofa,” said Priya. She later blacked out, collapsing after a grocery run. Her heart rate hit the roof and her blood pressure fluctuated dangerously.

It has been close to eight months since her brush with Covid-19, but her symptoms linger on. 

When the pandemic began, doctors had little idea of how Covid-19 affected patients over the long term. Priya’s cardiologist even ran an ECG ECG ECG An electrocardiogram records electric signal from your heart to check for different heart conditions after the incident in August; the test seemingly appeared normal.
