全球动态心电图监测市场前景预测(2020-2025年)
Holter monitors are small, battery-powered medical devices that record the activities
of the heart such as rate and rhythm. The Holter monitor was first developed at the
Holter research laboratory in
Helena Montana by
experimental physicists
Norman J. Holter and Bill
Glasscock, who initiated
work on radio telemetry in
1949. In the early 1950s, inspired by a suggestion from cardiologist Paul Dudley
White, efforts were shifted toward the development of a wearable cardiac monitoring
device. The Holter monitor was first commercially released in 1962. Since their
inception, these devices have been a cornerstone for diagnosing suspected
arrhythmias in patients across age groups. Conventional Holter monitors allow
continuous registration of three or more leads for 24–48 hours. Latest generation
Holter monitors allow continuous electrocardiogram (ECG) registration from 14 days
to 60 days. Such prolonged monitoring with Holter monitors will increase the
diagnostic yield of devices, especially for rhythm disturbances, which are infrequent
yet recurrent.

全球无人飞行器和无人机市场分析与预测(2020-2025年)
UAVs can be used for applications such as surveillance, monitoring, aerial patrolling, inspections, and
emergency rescue operations by remote controls or an on-board system for autonomous operations.
A UAS includes an UAV, camera, controller, sense and avoid system, navigation system, among
other hardware and software components. The scope of this report is focused on UAVs that are being
used by end users such as government and defense, commercial and consumer.

全球展望预测齿轮电动机市场(2021-2026年)
Geared motors are components that adjust the RPM of an engine, allowing it to run
at a certain speed. While gearheads serve as a torque multiplier that allows small
motors to achieve higher speeds, geared motors provide high torque at low speeds.
Geared motors can also be called gear reducers as, in effect, they are a combination
of a speed reducer with a motor normally serving as a gearbox to minimize speed to
allow more torque usable. Owing to their ability to deliver high torque at low speed,
geared motors are being increasingly used across several end-user industries. The
future dynamics of the geared motors market look strong, supported by rapid
progress and increasing investments in several end-user industries, mostly F&B,
power generation, material handling, and others.

全球左心耳封堵器市场展望和预测(2020-2025年)
Atrial fibrillation, also called AFib or AF, is an irregular and often rapid heart rate
that can increase the risk of strokes, heart failure (HF) and other heart-related
complications. During AF, the heart’s two upper chambers (the atria) beat chaotically
and irregularly without proper coordination with the two lower chambers (the
ventricles) of the heart. In AF, the irregular heartbeat results in ineffective blood
circulation out of the heart and through the body. This causes blood collecting, or
pooling, in the heart where clots can form. In case a clot travels to the brain, a stroke
can occur. People with AF are at 5-7 times higher risk of a stroke than the general
population.
