My heartbeats used to be generally between 90-100 but from last few days it is between 100-120. Sometimes it will be below 100 as well. My echo is normal. My doctor initially suggested to take propsan 40 whenever there is increase in heartbeat. I have anxiety issue as well. Should I take propsan 40 daily if my heartbeats are on higher side. Also can I stop this medicine after consulting doctor once my heartbeats are normal or this medicine needs to be taken even though my heartbeats become normal in future.
