Abstract

OBJECTIVE: Verapamil and adenosine are the most common agents used to treat paroxysmal supraventricular tachycardia (PSVT). We performed a systematic review and meta-analysis to determine the relative effectiveness of these drugs and to examine their respective adverse effect profiles. METHODS: We searched MEDLINE, EMBASE, CINAHL, the Cochrane database, and international clinical trial registers for randomized controlled trials comparing adenosine (or adenosine compounds) with verapamil for the treatment of PSVT in stable adult patients. The primary outcome was rate of reversion to sinus rhythm. Secondary outcome was occurrence of pooled adverse events. Odds ratios and 95% confidence intervals (CIs) were calculated using a random effects model (RevMan v5). RESULTS: Eight trials were appropriate and had the available data. The reversion rate for adenosine was 90.8% (95% CI: 87.3-93.4%) compared with 89.9% for verapamil (95% CI: 86.0-92.9%). The pooled odds ratio for successful reversion was 1.27 (95% CI: 0.63-2.57) favouring adenosine. This was not statistically significant. There was a higher rate of minor adverse effects described with adenosine (16.7-76%) compared with verapamil (0-9.9%). The rate of hypotension was lower with adenosine [0.6% (95% CI: 0.1-2.4%)] compared with verapamil [3.7% (95% CI: 1.9-6.9%)]. CONCLUSION: Adenosine and verapamil have similar efficacy in treating PSVT. Adenosine has a higher rate of minor adverse effects, and of overall adverse effects, whereas verapamil has a higher rate of causing hypotension. A decision between the two agents should be made on a case-by-case basis and ideally involve informed discussion with the patient where appropriate.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
