I’m 46 years old, healthy and have never, ever had any heart trouble. However, three times in the last six months I’ve had to go to Emergency because my heart starts jumping and racing and I feel like I could black out. I’ve now seen two cardiologists who think they should do surgery to cut the electrical channels in my heart. But I’m young and healthy–my periods are even regular but I’m getting night sweats now and having much worse premenstrual symptoms, cramps and heavy periods. Please help! I’m scared.
