Can Abnormal Thyroid Cause Heart Palpitation And Bundle Branch Block?

Hi i have been diagnosed with left bundle branch block. I am 47 years old female and never smoke or drank or drugs. Also have abnormal thyroid results 5.34 have been back and forth hypo and hyper thyroid many times. Can this be a link to heart palpatations and perhaps the bundle branch block. Im a nervous wreck and scared to death. Please shed some light. I am not having light headedness or short of breath. Just lots of panic attacks. :(

HI welcome to HCM.
Thyroid disorders can cause wide array of cardiovascular symptoms and disorders.you currently seem to have hypothyroid state.this can lead to a condition called lone atrial fibrillation which can present as heart palpitations.few thyroid disorders can mask as heart conduction disturbances like bundle branch blocks.they can subsequently lead to heart palpitations.correction of the underlying thyroid disturbance can lead to resolution of these symptoms.i suggest you to have a 2d screening echo and 24hr holter ecg.consult your cardiologist for further queries.
