I feel like you're asking for medical advice. But, no, I haven't personally experienced irregular heart-beat followed by low blood pressure, but I also don't regularly monitor those metrics beyond my smartwatch. Consuming too much caffeine, for me, just results in the regularly reported side effects. I do choose not to drink too much after 3 PM due to the long (5 hr) half-life/improved sleep quality.
