Key result
The esophageal Geiger-Müller tube technique correctly diagnosed 100% of left-to-right shunts (11 of 11), including 4 cases that were missed by conventional precordial techniques.

Does an esophageal Geiger-Muller tube technique improve the detection of left-to-right cardiac shunts compared to conventional precordial techniques in patients evaluated for shunts?
Absolute Event Rate: 100% vs 63.6%
The esophageal Geiger-Muller tube technique provides greater diagnostic accuracy for detecting left-to-right cardiac shunts compared to conventional precordial external counting methods.
Ira et al. (1965) conducted an observational in Left-to-right cardiac shunts (n=23). Esophageal Geiger-Müller tube technique vs. Conventional precordial techniques was evaluated on Detection of left-to-right shunts. The esophageal Geiger-Müller tube technique correctly diagnosed 100% of left-to-right shunts (11 of 11), including 4 cases that were missed by conventional precordial techniques.
