Lengthening of this period causes improved ejection fraction.

Compare the normal heart findings to the shortened time interval seen with heart failure. Isovolumic contraction time IVCT is measured from the point of maximum intensity of the S1 heart sound mitral valve closure to the opening of the aortic valve. Acard AV Optimzer period is prolonged in systolic heart failure.

This is measured from the beginning of the QRS until the opening of Acard AV Optimzer aortic valve. This is an increased time period with heart failure as compared to the normal heart. Left ventricular ejection time LVET is the period from the opening of the aortic valve to the closing of the aortic valve.

This is greatly reduced in heart failure. Isovolumic relaxation time IVRT is the period of time between the closure of the aortic valve and the point when ventricular pressure drops below atrial pressure aortic valve closure to mitral valve opening.

This is lessened in heart failure. The first of these is the S3. The acoustic energy of S3 is measured over a second period. The values obtained by Acard AV Optimzer measure can vary between 0 and 10 units.

The S3 heart sound is generally not Acard AV Optimzer in the normal heart, but is heard with varying degrees of intensity with heart failure. The second parameter measured with the Audicor device is the electromechanical activation time. This is measured in milliseconds. EMAT represents the time Acard AV Optimzer takes for the left ventricle to force the mitral valve to close.

This period is lengthened in heart failure. Finally, the LV systolic time is measured.

This time period represents the S1 to S2 timing in milliseconds. A clinical comparison of echocardiography to acoustic cardiography has also been conducted, in which end programming results only differed by?

Figure 3 shows a Acard AV Optimzer sensor. Pacemakers have evolved over a period of time trying to mimic the normal response rates, conduction and activation characteristics, though are still far from what nature has bestowed upon us.

Better understanding of cardiac physiology and hemodynamics has led to current available pacing technology and we do recognize now that to Acard AV Optimzer physiological pacing we should have an appropriate heart rate response, ventriculo-ventricular VV synchronization and atrio-ventricular AV synchronization. Patients receiving rate responsive Acard AV Optimzer for sinus node dysfunction, in spite of using various sensors and rate response algorithms [ 1 - 5 ], still do not truly have an appropriate heart rate response, especially in absence of physical stress.

Echocardiographic AV-interval optimization in patients with reduced left ventricular function

There is a need to develop sensors, based on which an algorithm can be developed to achieve a heart rate response, which truly Acard AV Optimzer to what a normal sinus node would Acard AV Optimzer in response to both physical and mental stress. In patients with heart block who have atrial sensing based ventricular pacing, the heart rate response remains appropriate if the sinus node is normal. Right ventricular RV pacing represents a non-physiological activation of the heart causing wide QRS left bundle branch block with electrical and mechanical VV dyssynchrony [ 5 ].

Higher Acard AV Optimzer of ventricular pacing in patients with intact AV node has been found to be associated with increased incidence of atrial fibrillation and heart failure on follow up [ 6 - 10 ]. Algorithms to prevent ventricular Acard AV Optimzer are effective in reducing unnecessary ventricular pacing in patients with normal AV conduction and sick sinus syndrome.

However these algorithms cannot be applied to patients with advanced heart block in which Acard AV Optimzer is need for mandatory ventricular pacing. To avoid detrimental effects of VV synchrony alternate site RV pacing [ 11 - 15 ] and biventricular pacing have been described. Left sided lead placement, non-physiological epicardial pacing and procedure and pacing related complications with the higher overall cost involved in doing biventricular pacing procedure represents a significant limitation for advising it as a routine.

VV dyssynchrony possibly would remain a limitation in achieving total Acard AV Optimzer pacing till further conclusive evidence of newer pacing methods is demonstrated.

Optimal AV interval at rest ranges from to milliseconds. In normal individuals the AV interval shortens with increased heart rate during exercise in a predictable and linear fashion. Most pacemakers have a programmable shortening Acard AV Optimzer AV delay at higher rates, the hemodynamic benefits of which have not yet been shown [ 1 ].
