Insights

Left bundle branch area pacing (LBBAP) can induce left ventricular outflow tract (LVOT) obstruction in hypertrophic cardiomyopathy (HCM) patients. Adjusting pacing settings, like switching from bipolar to unipolar, can resolve this obstruction and improve symptoms.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Cardiovascular Imaging

Background:

  • Left bundle branch area pacing (LBBAP) is a safe pacing strategy for non-obstructive hypertrophic cardiomyopathy (HCM).
  • The impact of LBBAP on left ventricular outflow tract (LVOT) obstruction in predisposed patients is not well understood.

Data Reporting and Recording01:24

Data Reporting and Recording

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Mass Spectrometry: Branched Alkane Fragmentation01:29

Mass Spectrometry: Branched Alkane Fragmentation

This lesson delves into the mass spectrometry of branched alkane fragmentation. Branched alkanes possess secondary or tertiary carbon atoms, which generate relatively stable carbocations if the cleavage occurs at the branching point. The high stability of carbocations drives the instant fragmentation of branched alkanes. Accordingly, the branched alkane's molecular ion peak is very weak or invisible in the mass spectra, especially in comparison to a linear alkane.

Generation of Straight or Branched Actin Filaments01:14

Generation of Straight or Branched Actin Filaments

The straight or branched structure formation of actin filaments is controlled by nucleating proteins such as the formins and Arp2/3 complex. Formin-mediated assembly results in straight filaments, whereas Arp2/3 protein complex-mediated assembly results in branched actin filaments.
Arp2/3 Complex
Arp2/3 complex is a seven-subunit complex consisting of two proteins similar to actin- Arp2 and Arp3, and five other subunits that help keep Arp2 and Arp3 inactive. When required, the complex is...
