The drug was given intravenously in 1 mg increments every minute under continuous monitoring of electrocardiogram and blood pressure. Endpoints for the administration of verapamil were the following: reversion to sinus rhythm; a ventricular rate slower than 100\/min; hypotension; a pulmonary capillary wedge pressure rising above 15 mm Hg; signs of intolerance; a maximum dose of 20 mg. Reversion to sinus rhythm was observed in 7\/8 patients in atrial flutter and in 1\/8 patients in atrial fibrillation; in all the ventricular rate could be slowed below 100\/min without untoward effects.<\/jats:p>","DOI":"10.1161\/01.cir.57.4.751","type":"journal-article","created":{"date-parts":[[2012,6,11]],"date-time":"2012-06-11T23:57:40Z","timestamp":1339459060000},"page":"751-755","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":55,"title":["Verapamil in the management of supraventricular tachyarrhythmias occurring after a recent myocardial infarction."],"prefix":"10.1161","volume":"57","author":[{"given":"F","family":"Hagemeijer","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","container-title":["Circulation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ahajournals.org\/doi\/pdf\/10.1161\/01.CIR.57.4.751","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T15:10:05Z","timestamp":1715526605000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.CIR.57.4.751"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1978,4]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1978,4]]}},"alternative-id":["10.1161\/01.CIR.57.4.751"],"URL":"https:\/\/doi.org\/10.1161\/01.cir.57.4.751","relation":{},"ISSN":["0009-7322","1524-4539"],"issn-type":[{"value":"0009-7322","type":"print"},{"value":"1524-4539","type":"electronic"}],"subject":[],"published":{"date-parts":[[1978,4]]},"assertion":[{"value":"1978-04-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
