38-yo female. I have been referred to a cardiologist, neurologist, and a sleep clinic after feeling weak, nearly fainting and having blackouts, all starting about a month ago. Holter monitor (48 hour) results:
General:
192680 QRS complexes
504 Ventricular beats (<1%)
33 Supraventricular beats (<1%)
2% of total time classified as noise
Ventriculars (V,F,E,I)
504 Isolated
0 Couplets
0 Bigeminal cycles
0 Runs totaling 0 beats
Heart Rates
42 Minimum at 5:11
68 Average
150 Maximum at 8:05
8162 Beats in tachycardia, 4% total
54446 Beats in bradycardia, 28% total
1.54 Seconds Max RR at 16:04
Supraventriculars (S,J,A)
31 isolated
1 couplets
0 bigeminal cycles
0 runs totaling 0 beats
Interpretation
Underlying sinus rhythm with intermittent episodes of sinus bradycardia and sinus tacycardia with rates from 42 to 150 bpm. Occasional isolated vpbs, no V. tachycardia, very rare isolated apbs with one a. couplet, no svt. No important pauses. No significant st shift. Symptoms noted on diary correlated with isolated vpbs.
History: Current bloodwork normal. Significant head injury/whiplash 2 years ago. CT scan and MRI of head showed no permanent damage, but no such tests done on neck. Gestiational diabetes with first child, 12 years ago. Lots of heart disease in family history.
Questions: Any comments on the significance of the results? Could left vagus nerve irritation cause anything like this? What about sleeping in the same bed with someone who has pretty bad untreated sleep apnea? What should I ask the doctors, or be sure to tell them?
Thanks in advance.
