Interventions

Handgrip

Find Handgrip in Maneuvers. Isometric effort raises systemic vascular resistance and sympathetic drive. Increased afterload can enlarge fixed MR/AR or left-to-right VSD flow; dynamic LVOT obstruction usually decreases. MVP click timing and fixed MR intensity need not move together.

Overview

Open Interventions → Maneuvers. Choose Off, Active. Effect levels and flow targets represent illustrative modeled responses; they are not clinical dose instructions.

Isometric effort raises systemic vascular resistance and sympathetic drive. Increased afterload can enlarge fixed MR/AR or left-to-right VSD flow; dynamic LVOT obstruction usually decreases. MVP click timing and fixed MR intensity need not move together.

The paused reference covers the route (Supervised sustained isometric handgrip, without breath holding.), example doses/settings, indications, adverse effects, contraindications/precautions and monitoring. These details are available after the intervention is selected.

What to monitor in the reference: ECG, BP, symptoms, filling pressures and gradients; no new ischemic ECG injury is inferred from this maneuver.

Step by step

  1. Inspect the untreated disease and active treatment count.
  2. Apply the intervention and compare pressures, forward flow, rhythm and congestion.
  3. Pause for its full reference; use Off or Interventions Reset to restart the comparison.
