A preliminary multi variable linear regression analysis on ECG chest Lead I from 10 selected far-field bipolar leads along the left arm, indicated that 3 of them in the LUA were relevant and worth evaluating in more detail from a heart rhythm information perspective.To derive a good and ...
Ventricular pacing requires implantation of a conventional pacing lead into a small hypertrophied right sided chamber, which is the morphologic left ventricle. The lead, by fluoroscopic criteria, may not appear to be at the ventricular apex (Figure 7B). The 12-lead ECG demonstrates a right bundle...
The presence of LBB area capture was tested with the aid of the 12 lead ECG system connected to the standard TMT machine (1). Conduction system capture was also assessed using modified V1 and V6 leads connected to the PSA for measurement of V6 left ventricular activation time (LVAT)(2) ...

The ratio of lung to body weight, an index of left-sided heart failure, was slightly but significantly increased in the HT and HT+DM groups Cardiac ACE and AT1R expression to a similar extent as compared with that in the control group Cardiac ACE expression and AT1R mRNA levels were ...
such as right-sided heart failure with preserved EF, valve pathologies, atrial/ventricular arrhythmias, or bradyarrhythmia; severe hypotension with ACE inhibitor use is not rare. There may be multiorgan involvement, involving nephrotic syndrome, hepatomegaly/ splenomegaly, periorbital bruising (“panda...
Segments were summarized across the above age and LVEF groups. All tests were 2-sided, and a p-value < 0.05 was considered statistically significant. SAS version 9.2 (SAS Institute Inc., Cary, NC) was used for all analyses. Results Patient stratification A total of 330 males, ages 6...
LA LGE scans were performed 20 minutes after bolus injection of 0.2 mmol/kg gadobutrol (Gadovist, Bayer, Berlin, Germany), with a maximum of 15 mmol in total. The LA LGE scan consisted of a free-breathing respiration-navigator-gated 3D FLASH sequence with FatSat and ECG-gating (en...
ECG = electrocardiogram; CRT = cardiac resynchronization therapy; RA = right atrial; RV = right ventricular; Q-LV = interval from QRS onset to latest LV electrogram; QRSd = QRS duration; S-QRS = interval from stimulus to QRS onset; STIM = stimulation signal; VT = ventricular tachycardia....
(ECG)-gated helical acquisition, which increases the radiation significantly. Postprocessing is with either a volume threshold approach or, similar to CMR, myocardial analysis is automated but most times requires manual adjustment (Fig. 39.3). In a study that compared accuracy and reproducibility of...
