Electrophysiology / HeartLogic™ Heart Failure Diagnostic / Multi-Sensor Technology
 

Multi-Sensor Technology

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.

HeartLogic Sensors

 
Icon of the HeartLogic Heart Sounds Sensor
Heart Sounds*
Reveals signs of elevated filling pressure and weakened ventricular contraction via S3 and S1 heart sounds, respectively.
Icon of the HeartLogic Thoracic Impedance Sensor
Thoracic Impedance
Measures impedance between electrodes on the RV lead and the pulse generator, which is indicative of fluid accumulation and pulmonary edema.
Icon of the HeartLogic Respiration Sensor
Respiration
Monitors respiratory patterns associated with shortness of breath. In particular, it monitors respiratory rate and rapid shallow breathing via RSBI (rapid shallow breathing index), which is a ratio of respiratory rate (RR) to tidal volume.
Icon of the HeartLogic Heart Rate Sensor
Heart Rate
Monitors night heart rate, captured between midnight to 6 a.m., which for most patients is indicative of the resting heart rate.
Icon of the HeartLogic Activity Sensor
Activity
Shows the number of hours per day a patient is active and reflects the patient’s overall status and fatigue.

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.

Icon of the HeartLogic Sleep Incline Diagnostic Trend
Sleep Incline
Measures the angle between the patient’s torso and the horizontal plane during a sleep period specified by the patient.
Icon of the HeartLogic AT/AF Burden Diagnostic Trend
AT/AF Burden
Displays the total amount of time spent in an atrial tachy response (ATR) mode switch, in hours per day.
Icon of the HeartLogic V Therapy Diagnostic Trend
V Therapy
Provides an abbreviated summary of antitachycardia pacing (ATP) and shock therapy type delivered each day: ATP (dot) or shock (electrical shock sign).
Icon of the HeartLogic % LV Placed Diagnostic Trend
% LV Placed
Monitors the percentage of cardiac beats paced with a left ventricular (LV) lead per day.**
Icon of the HeartLogic Weight Diagnostic Trend
Weight
Displays daily patient weight data collected by an external weight scale via the LATITUDE™ NXT Remote Patient Management System.

“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.”
