Summary
Oleander plant poisoning mimics digoxin toxicity, causing heart block and ventricular arrhythmias. Early identification of specific electrocardiogram patterns is crucial for prompt emergency treatment in oleander intoxication cases.
Area of Science:
- Toxicology
- Cardiology
- Plant Chemistry
Background:
- Oleander (Nerium oleander and Thevetia peruviana) is frequently used for self-harm in India.
- Its active compounds are cardiac glycosides, leading to toxicity similar to digoxin.
- Cardiac toxicity manifests as heart block and ventricular arrhythmias.
Observation:
- Presents two cases of oleander intoxication.
- Details the electrocardiographic patterns observed in patients with Nerium oleander and Thevetia peruviana poisoning.
Findings:
- Oleander intoxication presents with a distinct electrocardiographic pattern.
- This pattern is indicative of cardiac glycoside-like toxicity, including heart block and arrhythmias.
Implications:
- Early recognition of specific ECG findings in oleander poisoning is vital.
- Prompt diagnosis facilitates timely emergency management and improves patient outcomes.
- Understanding the toxicological profile aids in managing cardiac complications.

An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.

Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

01:28Disturbances in Heart Rhythm
956
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow...

798
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

An electrocardiogram (ECG)graphically represents the heart's electrical activity on ECG paper or a monitor.
Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....

The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase...
