I'm a bit confused and worried. I only took one sylate and now I've missed my period, and it turns out I'm pregnant. I don't get it because I thought all the days I was with my husband this month and last month were supposed to be safe days. Can you help me understand what might have happened?

Borderline Short PR Interval_

1. _Definition*: A PR interval measures the time between the onset of the P wave and the start of the QRS complex. A borderline short PR interval is typically considered to be between 120-140 milliseconds.
2. _Causes*: A borderline short PR interval can be caused by various factors, including:
   • Enhanced atrioventricular (AV) node conduction
   • Wolff-Parkinson-White (WPW) syndrome
   • Lown-Ganong-Levine (LGL) syndrome
   • Cardiac electrolyte imbalances
3. _Treatment*: Treatment depends on the underlying cause. If the borderline short PR interval is caused by an accessory electrical pathway (WPW or LGL syndrome), treatment may involve:
   • Catheter ablation to destroy the accessory pathway
   • Medications to regulate heart rhythm
   • Pacemaker implantation (in some cases)
4. _Worry level*: A borderline short PR interval is generally not a cause for concern. However, it's essential to consult a cardiologist to determine the underlying cause and receive proper guidance.
