1) Lungs: Lungs are frequently involved in acute COVID-19 infection, leading to symptoms of shortness of breath and low oxygen saturation in the body. Long COVID patients can also have symptoms of shortness of breath, dry cough, productive cough, and gasping for air.
2) Heart: Sharp chest pain, fluttering, racing of the heartbeat, lightheadedness with change in posture, and burning pain in the chest are a few of the symptoms of long COVID.
Recommendations: One should Consult the Physician if there are persistent symptoms. Initial investigations in the form of ECHO, X ray Chest, and Holter monitor can be offered to the patient. There is no treatment available for the long COVID. Rehab and supervised exercise program has been helpful in a few cases.

Holter monitor is quite efficient in detecting this correlation
My Long Covid update 14 months: Having a chronic illness is disheartening . I’m getting better than I’ve been, but nowhere near how I was before. My short term memory has improved but I’m still glitchy. My heart beat is irregular.
Racing heartbeat has become part of my life ,ever since i have caught covid,in 2021.
Hearing from others too who suffer from long Coronavirus validates that I’m not crazy. It’s been over 2 years for me. My balance and memory is the worst. Struggle most days and no end in sight.
