Holter Monitor: 24-Hour Monitoring01:23

Holter Monitor: 24-Hour Monitoring

1.2K
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...

Pulse rhythm01:30

Pulse rhythm

1.2K
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...

Sleep-Wake Cycles

2.5K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Stages of Sleep01:22

Stages of Sleep

1.1K
Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...

Summary
This summary is machine-generated.

Sleep duration in pregnant women averaged 7.2 hours and decreased with gestational age. Activity trackers (ATD) showed insufficient sleep (<7 hours) was linked to more daily steps but not other adverse outcomes.

Area of Science:

  • Obstetrics and Gynecology
  • Sleep Medicine
  • Wearable Technology in Health

Background:

  • Understanding sleep patterns during pregnancy is crucial for maternal and neonatal well-being.
  • Activity-tracking devices (ATD) offer objective measures of sleep duration and physical activity.
  • Previous research has explored sleep changes in pregnancy, but objective, continuous data across gestation is limited.

Observation:

  • A cohort of 94 pregnant women used ATDs to track sleep duration and daily steps.
  • Mean sleep duration was 7.2 ± 2.4 hours, decreasing significantly with advancing gestational age.
  • Women with insufficient sleep (<7 hours) exhibited higher median daily steps compared to those with sufficient sleep (≥7 hours).

Findings:

  • Gestational age was statistically significantly associated with mean hours of sleep (β = -0.02, p < 0.001).
  • No significant differences were observed in sedentary time, gestational weight gain, pregnancy-associated hypertension, gestational diabetes, delivery gestational age, cesarean delivery, or mean birthweight between sleep groups.
  • Insufficient sleep (<7 hours) was associated with increased daily steps (p < 0.01), but not other adverse maternal or neonatal outcomes.

Implications:

  • Objective ATD data reveals a decline in sleep duration as pregnancy progresses.
  • While insufficient sleep correlated with increased physical activity, its association with adverse pregnancy outcomes requires further investigation.
  • Future research should focus on refining ATD sleep measurement in pregnant populations and exploring the complex relationship between sleep duration, quality, and health outcomes.
