Arrhythmias Support Group
Cardiac arrhythmia is a group of conditions in which the muscle contraction of the heart is irregular or is faster or slower than normal. Some arrhythmias are life-threatening medical emergencies that can cause cardiac arrest and sudden death. Others cause aggravating symptoms, such as an awareness of a different heart beat, or palpitation, which can be annoying.
Please don't panic and allow a couple random episodes of tachycardia disable you, there is too much in life to enjoy. Remember Tachycardia is not unusual, everybody experiences it at some point. Additionally 140 bpm is nowhere near a point where one should worry. Until the rate is in the high 180's there is little concern.
I have VT frequently and while it can be annoying for most part I've learned to live with it. Your doctor is checking it out, so relax and try to put it in the back of your mind and move forward.
Good luck
