I am 51 years old male, in 2022 December I got stents in my three main arteries and now I’m on blood thinner medications, low cholesterol and low blood pressure medication. I’m doing well nothing is bothering me during my routine task and even exercising except once in a while I feel a little hiccup or a sinking feeling in my heart beati g which is not painful but it bothers me, sometime It’s like every hour or two and sometimes It’s once in a day can you explain? Should I be worried about? I did my regular stress test and ultrasound, ECG everything was fine as per my doctor .
