HeartLogic is the first and only FDA-approved heart failure diagnostic that uses multiple sensors to track physiological trends and combine them into one composite index. When the index crosses over a configurable threshold, HeartLogic provides a proactive alert to the clinician via the LATITUDE™ NXT Remote Patient Management System. These powerful insights may give your patient’s care team more time to adjust treatment, improve outcomes and turn reactive treatment into proactive care.
Reveals signs of elevated filling pressure and weakened ventricular contraction via S3 and S1 heart sounds, respectively.
Measures impedance between electrodes on the RV lead and the pulse generator, which is indicative of fluid accumulation and pulmonary edema.
Monitors night heart rate, captured between midnight to 6 a.m., which for most patients is indicative of the resting heart rate.
Additional Diagnostic Trends
Although the following diagnostic trends are not part of the HeartLogic algorithm, they can help clinicians understand the context of the HeartLogic alert.
Measures the angle between the patient’s torso and the horizontal plane during a sleep period specified by the patient.
Displays the total amount of time spent in an atrial tachy response (ATR) mode switch, in hours per day.
Monitors the percentage of cardiac beats paced with a left ventricular (LV) lead per day.**

“When you can use an integrated sensor, then the sensitivity and the specificity of that measure is a lot more focused in helping us ferret out the right population who’s going to have hospitalizations for heart failure.”
