Initial 12-lead electrocardiogram (and magnified view of lead II) from an 87-year-old woman showing normal sinus rhythm with first-degree atrioventricular block (PR interval 236 ms). The patient had presented with sudden and recurring episodes of lightheadedness that occurred while she was eating and drinking.
