Summary
Postoperative cardiovascular events after non-cardiac surgery are linked to inflammation, age, and pre-existing conditions. Holter monitoring identified rhythm and conduction issues, highlighting risks in older patients with hypertension.
Area of Science:
- Cardiology
- Perioperative Medicine
- Surgical Outcomes
Background:
- Cardiovascular complications significantly impact morbidity and mortality following non-cardiac surgery.
- Individualized patient assessment is crucial despite existing risk stratification scores.
Purpose of the Study:
- To identify new cardiac events occurring in the postoperative period after non-cardiac surgery.
Main Methods:
- 100 patients undergoing non-cardiac surgery were monitored using Holter, alongside clinical and biochemical markers (CRP, hscTnI).
- Assessment focused on perioperative cardiac events in patients with surgical pathologies.
Main Results:
- Postoperative atrial fibrillation (AF) occurred in 10% of patients, associated with longer surgery and anemia.
- Sinus pauses correlated with age, history of hypertension, and pre-existing AF.
- ST depression was linked to age, prolonged surgery, hypertension history, and intraoperative blood pressure fluctuations.
Conclusions:
- Advanced age, pre-existing conditions, inflammation, and prolonged surgery increase cardiovascular event risk post-non-cardiac surgery.
- Holter monitoring detected rhythm/conduction disorders and ST changes associated with inflammation and elevated cardiac markers.
- Further research is needed to understand the long-term impact of these cardiac complications.

259
Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

01:30Pulse rhythm
925
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...

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

3.2K
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.

01:25Correlation between ECG and Cardiac Cycle
8.3K
The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
