“When the heart doesn’t beat properly, it can’t pump blood effectively”


What is Arrhythmia?

The term “arrhythmia” refers to any change from the normal sequence of electrical impulses.  The electrical impulses may happen too fast, too slowly, or erratically – causing the heart to beat too fast, too slowly or erratically.  When the heart doesn’t beat properly, it can’t pump blood effectively.  When the heart doesn’t pump blood effectively, the lungs, brain and all other organs can’t work properly and may shut down or be damaged.

Almost everyone has felt their heart beat very fast, felt a “fluttering” in their chest or thought that their heart was “skipping a beat.”  These can be signs of arrhythmia, or abnormal or irregular heartbeat.

Arrhythmias can produce a broad range of symptoms, from barely perceptible to cardiovascular collapse and death.

When arrhythmias last long enough to affect how well the heart works, more serious symptoms may develop:

  • Fatigue
  • Dizziness
  • Lightheadedness
  • Fainting (syncope) or near-fainting spells
  • Rapid heartbeat or pounding
  • Shortness of breath
  • Chest pain
  • In extreme cases, collapse and sudden cardiac arrest

Our doctors can test and diagnose an Arrhythmia.

SLHV’s Arrhythmia Monitoring Services Include:

  • 24-hour support from a staff of cardiology technicians trained to recognize cardiac rhythms and assist patients of all ages.
  • Trend data, calculations of heart rates and rhythm strips included in daily reports for telemetry, event and holter monitors.
  • Auto-trigger and manual recording devices for cardiac event monitoring.
  • On-site patient training on the use of designated monitor.
  • Reports will be sent at the end of each monitor session.
  • Remote monitoring of loop recorders, pacemakers, defibrillators for rhythms and congestive heart failure with report, monthly or quarterly depending on device type and warranting conditions.

TeleSentry Telemetry Monitor

TeleSentry is a battery powered ambulatory ECG monitor which analyzes electrocardiographic signals.  The TeleSentry device classifies all detected heart beats and recognizes specific rhythm abnormalities.

All detected results, including annotations for every detected heart beat and ECG signal, are securely transmitted via a cellular telephone network to a remote server.

Transmissions by the TeleSentry device are accessible by the Arrhythmia Monitoring Center.  The data transmission is automatically triggered when abnormalities are detected.  The data will also be transmitted when manually triggered by the patient; or periodically if programmed for regular transmission.

The TeleSentry device is capable of detecting the following events:

  • Tachycardia
  • Bradycardia
  • Heart Rate Not Detected
  • Pause and Atrial Fibrillation
