I assumed it's a press drop after reading on the subject a bit. My normal pressure stand at 120/70. This drop happened very suddenly when I was at about 80% to 85% of my max bpm who is at 175. I feeled like the heart pump was cavitating, got nausea, I was like near fainting when I left the bike and was very tired in the day following this. During the drop phase, my heart rate continued to be high during about a minute and slowly decreased afterward. Thanks a lot for the response Livi.
