Having palpitations certainly needs further evaluation with possibly a 24 hr Holter monitor. This will help evaluate if your heart rate is elevated (average HR in a 24 hour period) and also if your QTc varies over the 24 hr period.
Knowing family history is also important.
Seeing a cardiologist or a cardiac electrophysiologist should be your next step.
