Although guidelines recommend that PTSMA should be performed in institutions with extensive experience, it ... |
23,088 | Usefulness of Temporary Pacing in Patients With New Left Bundle Branch Block During Transcatheter Aortic Valve Implantation. | New-onset left bundle branch block (NLBBB) is the most common complication after transcatheter aortic valve implantation (TAVI). Expert consensus recommends temporary transvenous pacemaker (TTVP) support for 24 hours in these patients. To date, no study has examined TTVP use during the index hospitalization in detail. ... |
23,089 | An Evaluation of Prehospital Adenosine Use. | Adenosine has been safely used by paramedics for the treatment of stable supraventricular tachycardia since the mid-1990s. However, there continues to be variability in paramedics' ability to identify appropriate indications for adenosine administration. As the first of a planned series of studies aimed at improving th... |
23,090 | A cardiac arrest on a spiked helmet electrocardiographic sign in anterior leads in a patient with a diagnosis of acute myocardial infarction: A case report. | In patients with critical heart disease, such as acute coronary syndrome, aortic dissection, and other diseases, ST-segment elevation is a relatively common finding on the electrocardiogram (ECG).
