Can Sinus Tachycardia Cause Heart Disease?

can sinus tachycardia cause heart dissease. im an only child im 36 and 4 months pregnant, i was diagnosed with it 4 years ago but had few attacks. since being pregnant it happens more often, at least once a week and more if i feel stressed. my father died of heart dissease, he was in his late fortys when he was diagnosed with angina, in his fiftys he had 3 heart attacks, at sixty he had a tripple heart bypass but passed away 2 years later.. his both parents died of heart dissease and so did his 1 sister and four brothers. ive seen a cardiologist recently but was told it was normall sinus tachycardia and the pregnancy has triggerd it off.. im nervous about the birth of my baby incase i have an attack of it during labour and it puts me or my baby in danger. what are the chances of my sinus tachycardia turning into heart dissease in a few years time.
