Tap water for electrocardiographic recording.

Tap water instead of electrode jelly for electrocardiographic recording.

Tap water tempest

You know the news isn’t going to be good when the report of a new study cites sources in City Hall rather than the scientific literature. That’s exactly how the story broke in February, reporting a link between tap water and miscarriages in a California study. On February 10, the Los Angeles Times warned its readers in a front page report that “drinking five or more glasses of cold tap water pe...

Serial electrocardiographic recording in aneurysmal subarachnoid hemorrhage.

We prospectively studied serial electrocardiograms in 61 patients with aneurysmal subarachnoid hemorrhage. Electrocardiographic changes were related to the initial level of consciousness, to subsequent events, and to outcome after 3 months. All 61 patients had at least one abnormal electrocardiogram, but cardiac disease did not contribute directly to morbidity or mortality. Fast rhythm disturba...

Ambulatory electrocardiographic recording in endurance athletes.

Data from ambulatory electrocardiographic recording in 35 highly trained endurance athletes and in 35 non-athletic controls of similar ages are given. The minimal, mean hourly, and maximal heart rates were significantly lower in the athletes. Thirteen athletes (37 . 1%) but only two controls (5 . 7%) had sinus pauses exceeding 2 . 0 seconds. First degree atrioventricular block was observed in 1...

Tap water for irrigation of lacerations.

This study was designed to compare the infection rates of simple lacerations irrigated with tap water versus sterile normal saline before repair. Patients with simple lacerations to an extremity that were less than 8 hours from injury were prospectively enrolled. Exclusions from the study were: dog bites, hand lacerations, immunocompromised patients, and those on antibiotics at the time of inju...
